Hans Verkuil 5126f2590b [media] v4l2-dev: add flag to have the core lock all file operations
This used to be the default if the lock pointer was set, but now that lock is by
default only used for ioctl serialization. Those drivers that already used
core locking have this flag set explicitly, except for some drivers where
it was obvious that there was no need to serialize any file operations other
than ioctl.

The drivers that didn't need this flag were:

drivers/media/radio/dsbr100.c
drivers/media/radio/radio-isa.c
drivers/media/radio/radio-keene.c
drivers/media/radio/radio-miropcm20.c
drivers/media/radio/radio-mr800.c
drivers/media/radio/radio-tea5764.c
drivers/media/radio/radio-timb.c
drivers/media/video/vivi.c
sound/i2c/other/tea575x-tuner.c

The other drivers that use core locking and where it was not immediately
obvious that this flag wasn't needed were changed so that the flag is set
together with a comment that that driver needs work to avoid having to
set that flag. This will often involve taking the core lock in the fops
themselves.

Eventually this flag should go and it should not be used in new drivers.

There are a few reasons why we want to avoid core locking of non-ioctl
fops: in the case of mmap this can lead to a deadlock in rare situations
since when mmap is called the mmap_sem is held and it is possible for
other parts of the code to take that lock as well (copy_from_user()/copy_to_user()
perform a down_read(&mm->mmap_sem) when a page fault occurs).

It is very unlikely that that happens since the core lock serializes all
fops, but the kernel warns about it if lock validation is turned on.

For poll it is also undesirable to take the core lock as that can introduce
increased latency. The same is true for read/write.

While it was possible to make flags or something to turn on/off taking the
core lock for each file operation, in practice it is much simpler to just
not take it at all except for ioctl and leave it to the driver to take the
lock. There are only a handful fops compared to the zillion ioctls we have.

I also wanted to make it obvious which drivers still take the lock for all
fops, so that's why I chose to have drivers set it explicitly.

Jesper Juhl 266e8ae37d [media] media, cx231xx: Fix double free on close
In cx231xx_v4l2_close() there are two calls to
cx231xx_release_resources(dev) followed by kfree(dev). That is a
problem since cx231xx_release_resources() already kfree()'s its
argument, so we end up doing a double free.

Easily resolved by just removing the redundant kfree() calls after the
calls to cx231xx_release_resources().

I also changed the 'dev = NULL' assignments (which are rather
pointless since 'dev' is about to go out of scope), to 'fh->dev = NULL'
since it looks to me that that is what was actually intended.
And I removed the 'dev = NULL' assignment at the end of
cx231xx_release_resources() since it is pointless.

Hans Verkuil 583aa3a9b5 [media] V4L2: Add per-device-node capabilities
If V4L2_CAP_DEVICE_CAPS is set, then the new device_caps field is filled with
the capabilities of the opened device node.

The capabilities field traditionally contains the capabilities of the physical
device, being a superset of all capabilities available at the several device
nodes. E.g., if you open /dev/video0, then if it contains VBI caps then that means
that there is a corresponding vbi node as well. And the capabilities field of
both the video and vbi nodes should contain identical caps.

However, it would be very useful to also have a capabilities field that contains
just the caps for the currently open device, hence the new CAP bit and field.

Thomas Petazzoni 7a6f6c29d2 [media] cx231xx: use URB_NO_TRANSFER_DMA_MAP on URBs allocated with usb_alloc_urb()
URBs allocated with usb_alloc_urb() are allocated from DMA-coherent
areas, and therefore it is not necessary to call dma_map_single() on
such buffers. Worst, on ARM, calling dma_map_single() on a
DMA-coherent buffer will trigger a BUG_ON() in
arch/arm/mm/dma-mapping.c.

Therefore, we mark all URBs allocated with usb_alloc_urb() with the
URB_NO_TRANSFER_DMA_MAP transfer_flags, so that the USB core does not
do dma_map_single()/dma_unmap_single() on those buffers.

This is similar to 882787ff8f for the
gspca driver, and has already been discussed on the linux-media list
in the past:

Mauro Carvalho Chehab 7528cd273e [media] cx231xx: Fix unregister logic
There are several weirdness at the unregister logic.

First of all, IR has a poll thread. This thread needs to be
removed, as it uses some resources associated to the main driver.
So, the driver needs to explicitly unregister the I2C client for
ir-kbd-i2c.

If, for some reason, the driver needs to wait for a close()
to happen, not all memories will be freed, because the free
logic were in the wrong place.

Also, v4l2_device_unregister() seems to be called too early,
as devices are still using it.

Finally, even with the device disconnected, there is one
USB function call that will still try to talk with it.

Thomas Petazzoni a116a05cb4 [media] cx231xx: fix crash after load/unload/load of module
The following sequence of commands was triggering a kernel crash in
cdev_get():

 modprobe cx231xx
 rmmod cx231xx
 modprobe cx231xx
 v4l2grab -n 1

The problem was that cx231xx_usb_disconnect() was not doing anything
because the test:

	if (!dev->udev)
		return;

was reached (i.e, dev->udev was NULL).

This is due to the fact that the 'dev' pointer placed as intfdata into
the usb_interface structure had the wrong value, because
cx231xx_probe() was doing the usb_set_intfdata() on the wrong
usb_interface structure. For some reason, cx231xx_probe() was doing
the following:

static int cx231xx_usb_probe(struct usb_interface *interface,
			     const struct usb_device_id *id)
{
        struct usb_interface *lif = NULL;
	[...]
        /* store the current interface */
        lif = interface;
	[...]
        /* store the interface 0 back */
        lif = udev->actconfig->interface[0];
	[...]
	usb_set_intfdata(lif, dev);
	[...]
	retval = v4l2_device_register(&interface->dev, &dev->v4l2_dev);
	[...]
}

So, the usb_set_intfdata() was done on udev->actconfig->interface[0]
and not on the 'interface' passed as argument to the ->probe() and
->disconnect() hooks. Later on, v4l2_device_register() was
initializing the intfdata of the correct usb_interface structure as a
pointer to the v4l2_device structure.

Upon unregistration, the ->disconnect() hook was getting the intfdata
of the usb_interface passed as argument... and casted it to a 'struct
cx231xx *' while it was in fact a 'struct v4l2_device *'.

The correct fix seems to just be to set the intfdata on the proper
interface from the beginning. Now, loading/unloading/reloading the
driver allows to use the device properly.

Arnaud Lacombe 3f5c14d3d3 [media] drivers/media: do not use EXTRA_CFLAGS
Usage of these flags has been deprecated for nearly 4 years by:

    commit f77bf01425
    Author: Sam Ravnborg <sam@neptun.(none)>
    Date:   Mon Oct 15 22:25:06 2007 +0200

        kbuild: introduce ccflags-y, asflags-y and ldflags-y

Moreover, these flags (at least EXTRA_CFLAGS) have been documented for command
line use. By default, gmake(1) do not override command line setting, so this is
likely to result in build failure or unexpected behavior.

Replace their usage by Kbuild's `{as,cc,ld}flags-y'.

Devin Heitmueller de99d5328c [media] cx231xx: Provide signal lock status in G_INPUT
Make use of the signal state registers to properly populate the signal lock
registers in the cx231xx driver.

This allows applications to know whether there is a signal present even in
devices which lack a tuner (since such apps typically won't call G_TUNER if
no tuner is present).

Devin Heitmueller 44ecf1df94 [media] cx231xx: Fix power ramping issue
On platforms that have CONFIG_HZ set to 100, the power ramp time effectively
ends up being 10ms.  However, on those that have a higher CONFIG_HZ, the time
ends up *actually* being 5ms, which doesn't allow enough time for the hardware
to be fully powered up before attempting to address it via i2c.

Change the constant to 10ms, which is long enough for the hardware to power
up, and won't really be anymore time than it was previously on platforms
with CONFIG_HZ being 100.

Credit goes to Mauro Carvalho Chehab and Gerd Hoffmann who previously
investigated this issue.

Tested with the Hauppauge USBLive 2, with which the problem was readily
reproducible after setting CONFIG_HZ to 1000.

Devin Heitmueller 992299e84a [media] Fix regression introduced which broke the Hauppauge USBLive 2
The following patch addresses the regression introduced in the cx231xx
driver which stopped the Hauppauge USBLive2 from working.

Confirmed working by both myself and the user who reported the issue
on the KernelLabs blog (Robert DeLuca).

At some point during refactoring of the cx231xx driver, the USBLive 2 device
became broken.  This patch results in the device working again.

Thanks to Robert DeLuca for sponsoring this work.

Mauro Carvalho Chehab 1990d50b58 [media] Stop using linux/version.h on most video drivers
All the modified drivers didn't have any version increment since
Jan, 1 2011. Several of them didn't have any version increment
for a long time, even having new features and important bug fixes
happening.

As we're now filling the QUERYCAP version with the current Kernel
Release, we don't need to maintain a per-driver version control
anymore. So, let's just use the default.

In order to preserve the Kernel module version history, a
KERNEL_VERSION() macro were added to all modified drivers, and
the extraver number were incremented.

I opted to preserve the per-driver version control to a few
pwc, pvrusb2, s2255, s5p-fimc and sh_vou.

A few drivers are still using the legacy way to handle ioctl's.
So, we can't do such change on them, otherwise, they'll break.
Those are: uvc, et61x251 and sn9c102.

The rationale is that the per-driver version control seems to be
actively maintained on those.

Yet, I think that the better for them would be to just use the
default version numbering, instead of doing that by themselves.

While here, removed a few uneeded include linux/version.h
