Merge tag 'media/v4.2-3' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media

Pull media fixes from Mauro Carvalho Chehab:

 - a regression fix at the videobuf2 core driver

 - fix error handling at mantis probing code

 - revert the IR encode patches, as the API is not mature enough.
   So, better to postpone the changes to a latter Kernel

 - fix Kconfig breakages on some randconfig scenarios.

Fabio Estevam 02387b5f25 [media] mantis: Fix error handling in mantis_dma_init()
Current code assigns 0 to variable 'err', which makes mantis_dma_init()
to return success even if mantis_alloc_buffers() fails.

Fix it by checking the return value from mantis_alloc_buffers() and
propagating it in the case of error.

Luis R. Rodriguez f5530d5af8 x86/mm/pat, drivers/media/ivtv: Move the PAT warning and replace WARN() with pr_warn()
On built-in kernels this warning will always splat, even if no ivtvfb
hardware is present, as this is part of the module init:

	if (WARN(pat_enabled(),
		 "ivtvfb needs PAT disabled, boot with nopat kernel parameter\n")) {

Fix that by shifting the PAT requirement check out under the code
that does the "quasi-probe" for the device.

This device driver relies on an existing driver to find its own devices,
it looks for that device driver and its own found devices, then uses
driver_for_each_device() to try to see if it can probe each of those
devices as a frambuffer device with ivtvfb_init_card().

We tuck the PAT requiremenet check then on the ivtvfb_init_card() call
making the check at least require an ivtv device present before
complaining.

Sakari Ailus 6d058c5643 [media] vb2: Only requeue buffers immediately once streaming is started
Buffers can be returned back to videobuf2 in driver's streamon handler. In
this case vb2_buffer_done() with buffer state VB2_BUF_STATE_QUEUED will
cause the driver's buf_queue vb2 operation to be called, queueing the same
buffer again only to be returned to videobuf2 using vb2_buffer_done() and so
on.

Add a new buffer state VB2_BUF_STATE_REQUEUEING which, when used as the
state argument to vb2_buffer_done(), will result in buffers queued to the
driver. Using VB2_BUF_STATE_QUEUED will leave the buffer to videobuf2, as it
was before "[media] vb2: allow requeuing buffers while streaming".

 - New driver for a PCI device: cobalt.  This driver is actually not
   sold in the market, but it is a good example of a multi-HDMI input
   device;

 - The dt3155 driver were promoted from staging;

 - The mantis driver got remote controller support;

 - New V4L2 driver for ST bdisp SoC chipsets;

 - Make sparse and smatch happier: several bugs were solved by fixing
   the issues reported by those static code analyzers.

 - Lots of new device additions, new features, improvements and cleanups
   at the existing drivers.

Mauro Carvalho Chehab 816de50d35 [media] saa7134: fix page size on some archs
On some archs, like tile, the PAGE_SIZE is not 4K. In the case
of tile arch, it can be either 16KB or 64KB.

Due to that, a warning is produced:
	drivers/media/pci/saa7134/saa7134.h:678:43: warning: large integer implicitly truncated to unsigned type [-Woverflow]

This is actually an error, as it will write trach to the DMA size
registers. The logic at saa7134-ts already does the right thing:

	saa_writeb(SAA7134_TS_DMA0, ((dev->ts.nr_packets-1)&0xff));
	saa_writeb(SAA7134_TS_DMA1, (((dev->ts.nr_packets-1)>>8)&0xff));
	/* TSNOPIT=0, TSCOLAP=0 */
	saa_writeb(SAA7134_TS_DMA2,
		((((dev->ts.nr_packets-1)>>16)&0x3f) | 0x00));

So, fix the driver to take larger page sizes into account.

Luis R. Rodriguez 1bf1735b47 x86/mm/pat, drivers/media/ivtv: Use arch_phys_wc_add() and require PAT disabled
We are burrying direct access to MTRR code support on
x86 in order to take advantage of PAT. In the future, we
also want to make the default behavior of ioremap_nocache()
to use strong UC, at which point the use of mtrr_add() on
those systems would make write-combining void.

In order to help both enable us to later make strong
UC default and in order to phase out direct MTRR access
code, port the driver over to the arch_phys_wc_add() API
and annotate that the device driver requires systems to
boot with PAT disabled, with the 'nopat' kernel parameter.

This is a workable compromise given that the hardware is
really rare these days, and perhaps only some lost souls
stuck with obsolete hardware are expected to be using this
feature of the device driver.

Jan Klötzke a96762da0c [media] mantis: add remote control support
The embedded UART is apparently used to receive decoded IR (RC5?) codes.
Forward these scan codes to the RC framework and (where known) add
corresponding mapping tables to translate them into regular keys.

This patch has been tested on a TechniSat CableStar HD2. The mappings of other
rc-maps were taken from Christoph Pinkl's patch
(http://patchwork.linuxtv.org/patch/7217/) and the s2-liplianin repository. The
major difference to Christoph's patch is a reworked interrupt handling of the
UART because the RX interrupt is apparently level triggered and requires
masking until the FIFO is read by the UART worker.

David Howells 0f91c9d6ba [media] TS2020: Calculate tuner gain correctly
The TS2020 and TS2022 tuners take an input from the demodulator indicating the
AGC setting on that component that is then used to influence the tuner's own
gain.  This should be taken into account when calculating the gain and signal
strength.

Further, the existing TS2020 driver miscalculates the signal strength as the
result of its calculations can exceed the storage capacity of the 16-bit word
used to return it to userspace.

To this end:

 (1) Add a callback function (->get_agc_pwm()) in the ts2020_config struct that
     the tuner can call to get the AGC PWM value from the demodulator.

 (2) Modify the TS2020 driver to calculate the gain according to Montage's
     specification with the adjustment that we produce a negative value and
     scale it to 0.001dB units (which is what the DVBv5 API will require):

     (a) Callback to the demodulator to retrieve the AGC PWM value and then
     	 turn that into Vagc for incorporation in the calculations.  If the
     	 callback is unset, assume a Vagc of 0.

     (b) Calculate the tuner gain from a combination of Vagc and the tuner's RF
     	 gain and baseband gain settings.

 (3) Turn this into a percentage signal strength as per Montage's
     specification for return to userspace with the DVBv3 API.

 (4) Provide a function in the M88DS3103 demodulator driver that can be used to
     get the AGC PWM value on behalf of the tuner.

 (5) The ts2020_config.get_agc_pwm function should be set by the code that
     stitches together the drivers for each card.

     For the DVBSky cards that use the M88DS3103 with the TS2020 or the TS2022,
     set the get_agc_pwm function to point to m88ds3103_get_agc_pwm.

I have tested this with a DVBSky S952 card which has an M88DS3103 and a TS2022.

Takeshi Yoshimura 25e057fdde [media] ddbridge: Do not free_irq() if request_irq() failed
My static checker detected that free_irq() is called even after
request_irq() failed in ddb_probe(). In this case, the kernel may try to
free dev->pdev->irq although the IRQ is not assigned. This event rarely
occurs, but always introduces a warning if it happens.

"goto fail1" always results in disabling enabled MSI and releasing a
requested IRQ. It seems like the former handling is necessary. So I added
a conditional branch before the free_irq() (stat == 0 means request_irq()
succeeds).

Mauro Carvalho Chehab 0df289a209 [media] dvb: Get rid of typedev usage for enums
The DVB API was originally defined using typedefs. This is against
Kernel CodingStyle, and there's no good usage here. While we can't
remove its usage on userspace, we can avoid its usage in Kernelspace.

So, let's do it.

This patch was generated by this shell script:

	for j in $(grep typedef include/uapi/linux/dvb/frontend.h |cut -d' ' -f 3); do for i in $(find drivers/media -name '*.[ch]' -type f) $(find drivers/staging/media -name '*.[ch]' -type f); do sed "s,${j}_t,enum $j," <$i >a && mv a $i; done; done

While here, make CodingStyle fixes on the affected lines.

	drivers/media/pci/ivtv/ivtv-fileops.c:1026 ivtv_open() warn: suspicious bitop condition

Those are false positives, but it is not hard to get rid of them by
using a different way to evaluate the macro, splitting the logical
boolean evaluation from the bitmap one.

Mauro Carvalho Chehab c65171cf6f [media] bt8xx: remove needless check
As reported by smatch:
	drivers/media/pci/bt8xx/dst_ca.c:323 ca_get_message() warn: this array is probably non-NULL. 'p_ca_message->msg'
	drivers/media/pci/bt8xx/dst_ca.c:498 ca_send_message() warn: this array is probably non-NULL. 'p_ca_message->msg'

Those two checks are needless/useless, as the ca_msg struct is
declared as:
typedef struct ca_msg {
        unsigned int index;
        unsigned int type;
        unsigned int length;
        unsigned char msg[256];
} ca_msg_t;

So, if the p_ca_message pointer is not null, msg will also be
not null.

Hans Verkuil 86bad00a2f [media] cobalt: fix irqs used for the adv7511 transmitter
The interrupt bit assignments use for the adv7511 were off by one.
This means that the current scheme (bit << (4 * stream_index)) can
no longer be used.

Fix this by precalculating and storing the correct masks in the
cobalt_stream struct.

This wasn't noticed before because the adv7511 interrupts are very
rare. But for CEC support these interrupts are essential, so this made
me realize that it wasn't working correctly.

Fix the 0x0x prefix in integer constants.

In this case a padding 0 must also be inserted to make the constants
look like all the other 16 bits ones.

Hans Verkuil 85756a069c [media] cobalt: add new driver
The cobalt device is a PCIe card with 4 HDMI inputs (adv7604) and a
connector that can be used to hook up an adv7511 transmitter or an
adv7842 receiver daughterboard.

This device is used within Cisco but is sadly not available outside
of Cisco. Nevertheless it is a very interesting driver that can serve
as an example of how to support HDMI hardware and how to use the popular
adv devices.

Brendan McGrath 77978089dd [media] saa7164: use an MSI interrupt when available
Enhances driver to use an MSI interrupt when available.

Adds the module option 'enable_msi' (type bool) which by default is
enabled. Can be set to 'N' to disable.

Fixes (or can reduce the occurrence of) a crash which is most commonly
reported when both digital tuners of the saa7164 chip is in use. A
reported example can be found here:

Mauro Carvalho Chehab 6139ebc658 [media] saa7134: fix CodingStyle issues on the lines touched by pr_foo refactor
Several lines touched by the pr_foo refactoring patches are not
following the Linux Coding style.

While we won't be fixing the style globally at the driver, we should,
at least, fix on the lines we touched.

Basically, this patch add (or remove) whitespaces and blank lines
where needed.

No functional changes.

The debug macros are not properly defined, as they generate warnings
like:

ERROR: Macros with complex values should be enclosed in parentheses
+#define core_dbg(fmt, arg...)    if (core_debug) \

Use do { } while (0) for those macros.
