Mauro Carvalho Chehab bb69ee27b9 [media] Fix build when drivers are builtin and frontend modules
There are a large number of reports that the media build is
not compiling when some drivers are compiled as builtin, while
the needed frontends are compiled as module.

On the last one of such reports:
	From: kbuild test robot <fengguang.wu@intel.com>
	Subject: saa7134-dvb.c:undefined reference to `zl10039_attach'

The .config file has:

	CONFIG_VIDEO_SAA7134=y
	CONFIG_VIDEO_SAA7134_DVB=y
	# CONFIG_MEDIA_ATTACH is not set
	CONFIG_DVB_ZL10039=m

And it produces all those errors:

>> saa7134-dvb.c:(.text+0x3479c1): undefined reference to `zl10039_attach'

This is happening because a builtin module can't use directly a symbol
found on a module. By enabling CONFIG_MEDIA_ATTACH, the configuration
becomes valid, as dvb_attach() macro loads the module if needed, making
the symbol available to the builtin module.

While this bug started to appear after the patches that use IS_DEFINED
macro (like changeset 7b34be71db), this
bug is a way ancient than that.

The thing is that, before the IS_DEFINED() patches, the logic used to be:

       && defined(MODULE))
struct dvb_frontend *zl10039_attach(struct dvb_frontend *fe,
					u8 i2c_addr,
					struct i2c_adapter *i2c);
static inline struct dvb_frontend *zl10039_attach(struct dvb_frontend *fe,
					u8 i2c_addr,
					struct i2c_adapter *i2c)
{
	printk(KERN_WARNING "%s: driver disabled by Kconfig\n", __func__);
	return NULL;
}

The above code, with the .config file used, was evoluting to FALSE
(instead of TRUE as it should be, as CONFIG_DVB_ZL10039 is 'm'),
and were adding the static inline code at saa7134-dvb, instead
of the external call. So, while it weren't producing any compilation
error, the code weren't working either.

So, as the overhead for using CONFIG_MEDIA_ATTACH is minimal, just
enable it, if MODULES is defined.

This option is a merge of both analog TV and DVB CUSTOMISE.

At the merge, the dependencies were not done right: the menu
currently appears only for analog TV. It should also be opened
for digital TV. As there are other I2C devices there (flash
devices, etc) that aren't related to either one, it is better
to make it generic enough to open for all media devices with

That simplifies the life for users, as they can just keep

Mauro Carvalho Chehab 8cfd9dccf2 [media] media: Remove VIDEO_MEDIA Kconfig option
In the past, it was possible to have either DVB or V4L2 core
as module and the other as builtin. Such config never make much
sense, and created several issues in order to make the Kconfig
dependency to work, as all drivers that depend on both (most
TV drivers) would need to be compiled as 'm'. Due to that,
the VIDEO_MEDIA config option were added.

Instead of such weird approach, let's just use the MEDIA_SUPPORT
=y or =m to select if the media subsystem core will be either
builtin or module, simplifying the building system logic.

Also, fix the tuners configuration, by enabling them only if
a tuner is required. So, if just webcam/grabbers support is
selected, no tuner option will be selected. Also, if only digital
TV is selected, no analog tuner support is selected.

That removes the need of using EXPERT customise options, when
analog TV is not selected.

Arnd Bergmann 0edf2e5e2b [media] v4l: kill the BKL
All of the hard problems for BKL removal appear to be solved in the
v4l-dvb/master tree. This removes the BKL from the various open
functions that do not need it, or only use it to protect an
open count.

The zoran driver is nontrivial in this regard, so I introduce
a new mutex that locks both the open/release and the ioctl
functions. Someone with access to the hardware can probably
improve that by using the existing lock in all cases.

Finally, all drivers that still use the locked version of the
ioctl function now get called under a new mutex instead of
the BKL.

Arnd Bergmann 6de5bd128d BKL: introduce CONFIG_BKL.
With all the patches we have queued in the BKL removal tree, only a
few dozen modules are left that actually rely on the BKL, and even
there are lots of low-hanging fruit. We need to decide what to do
about them, this patch illustrates one of the options:

Every user of the BKL is marked as 'depends on BKL' in Kconfig,
and the CONFIG_BKL becomes a user-visible option. If it gets
disabled, no BKL using module can be built any more and the BKL
code itself is compiled out.

The one exception is file locking, which is practically always
enabled and does a 'select BKL' instead. This effectively forces
CONFIG_BKL to be enabled until we have solved the fs/lockd
mess and can apply the patch that removes the BKL from fs/locks.c.

Mauro Carvalho Chehab 039d40019f V4L/DVB (7898): Fix VIDEO_MEDIA Kconfig logic
If one of DVB_CORE or VIDEO_DEV is a module, the modules that can be used by
both DVB and V4L cores should also be a module, otherwise, it will break its
dependencies. This Kconfig logic implements the following:

CONFIG_VIDEO_DEV        CONFIG_DVB_CORE         CONFIG_VIDEO_MEDIA
        N                       N                       N
        N                       M                       M
        N                       Y                       Y
        M                       N                       M

Mauro Carvalho Chehab 7c91f0624a V4L/DVB(7767): Move tuners to common/tuners
There were several issues in the past, caused by the hybrid tuner design, since
now, the same tuner can be used by drivers/media/dvb and drivers/media/video.

Kconfig items were rearranged, to split V4L/DVB core from their drivers.

This patch removes zoran checks for VIDEO_V4L2, since this API is always
present, when V4L is selected.

Michael Krufky 8eb8ff3870 V4L/DVB (7483): tuner-simple: fix broken build dependency
tuner-simple is the only module that uses tuner-types - these will be
merged to a single module in the future.  For now, build both of them
if TUNER_SIMPLE is selected.

This fixes the following build warning, if tuner-simple is selected
without tuner-types:

WARNING: "tuner_count" [tuner-simple.ko] undefined!
WARNING: "tuners" [tuner-simple.ko] undefined!

Guennadi Liakhovetski 0705135e59 V4L/DVB (7237): Convert videobuf-dma-sg to generic DMA API
videobuf-dma-sg does not need to depend on PCI. Switch it to using generic
DMA API, convert all affected drivers, relax Kconfig restriction, improve
compile-time type checking, fix some Coding Style violations while at it.

Guennadi Liakhovetski 6d43cec87f V4L/DVB (7196): Lift videobuf-dma-sg's PCI dependency, until it is fixed
videobuf-dma-sg.c should be converted to the generic DMA API to make it
also useful for non-PCI configurations. Even now it can be used thanks
to compatibility macros in include/asm-generic/pci-dma-compat.h. This
has been verified to work on PXA270 CPU with the pxa_camera.c soc-camera
driver. For this the following temporary work-around is needed.

Michael Krufky 82b3083d26 V4L/DVB (7125): tuner: build tuner-types independently of tuner-core
tuner-types is needed for tuner-simple, and does not need to be bound
to tuner-core.  Any caller of tuner-simple, including tuner-core, needs
to pass a structure from tuner-types into tuner-simple at attach-time.

Export the two needed symbols from tuner-types for now, so that card-level
drivers can attach tuner-simple for hybrid dvb_frontend devices.  We will
remove this dependency altogether as tuner refactoring phase 3 progresses.
