From: Mauro Carvalho Chehab <mchehab@redhat.com>
This patch adds the capability of selecting between 4 different inputs
on vivi driver. Input 0 is the normal color bar, while inputs 1-3 are
modified color bars.
This allows testing input selection on userspace applications and
serves as an implementation model for other drivers.
The current approach allows a maximum of 10 different inputs, since the
input name generator assumes that we need just one digit to present the
input. It shouldn't be hard to modify it to present a bigger name of
inputs, but, in fact, it doesn't make much sense of doing it for this
test driver.

When enabling a shared IRQ line, then saa7134_irq handler could be invoked
before the driver had completely set up internal structures, due to a shared
interrupt line firing. Clear the saa7134 interrupt status reg, before
requesting the irq line, so that stale IRQ status isn't processed before the
internal structures are set up.
Marcin Slusarz recently brought this Oops to the attention of the v4l-dvb
lists and provided an initial analysis by investigating reports found here:

Register 0x2d has to be set differently in the saa7129 compared to the
saa7127. This was not done correctly, so S-Video was broken in certain
circumstances.
This fixes a regression introduced in 2.6.28.

Analog support for HVR-1250 has not been completed, but does exist for
the HVR-1800.
Since both cards use the same driver, it tries to create the analog
dev for both devices, which is not possible.
This causes a NULL error to show up in video_open and mpeg_open.
-Mark
Iterations through the cx23885_devlist must check for NULL
pointers as some supported devices only have DVB support at the moment.
Mark Jenks encoutered an Oops in a system with both an HVR-1250 and HVR-1800
installed.

If Hauppauge eeprom is corrupted, the driver returns tuner = 0, instead
of TUNER_ABSENT.
This makes the drivers to initialize tuner, instead of handling the
manual parameter.
Since the tuner core rejects that a tuner to have their type changed,
this breaks the manual tuner override.

Changeset 60b4bde48b36c0315ef41fd38c339b9c7e68c46f removed an unused
struct on zoran driver, when compiled with "Y".
However, as pointed by Jean Delvare <khali@linux-fr.org>, this is
neeeded when the driver is compiled as a module, since udev relies on it
to auto-load the module.

poll: allow f_op->poll to sleep
f_op->poll is the only vfs operation which is not allowed to sleep. It's
because poll and select implementation used task state to synchronize
against wake ups, which doesn't have to be the case anymore as wait/wake
interface can now use custom wake up functions. The non-sleep restriction
can be a bit tricky because ->poll is not called from an atomic context
and the result of accidentally sleeping in ->poll only shows up as
temporary busy looping when the timing is right or rather wrong.
This patch converts poll/select to use custom wake up function and use
separate triggered variable to synchronize against wake up events. The
only added overhead is an extra function call during wake up and
negligible.
This patch removes the one non-sleep exception from vfs locking rules and
is beneficial to userland filesystem implementations like FUSE, 9p or
peculiar fs like spufs as it's very difficult for those to implement
non-sleeping poll method.
While at it, make the following cosmetic changes to make poll.h and
select.c checkpatch friendly.
* s/type * symbol/type *symbol/ : three places in poll.h
* remove blank line before EXPORT_SYMBOL() : two places in select.c
Oleg: spotted missing barrier in poll_schedule_timeout()
Davide: spotted missing write barrier in pollwake()

i2c: Drop I2C_CLASS_CAM_DIGITAL
There are a number of drivers which set their i2c bus class to
I2C_CLASS_CAM_DIGITAL, however no chip driver actually checks for this

Check fops_get() return value
Several subsystem open handlers dereference the fops_get() return value
without checking it for nullness. This opens a race condition between the
open handler and module unloading.
A module can be marked as being unloaded (MODULE_STATE_GOING) before its
exit function is called and gets the chance to unregister the driver.
During that window open handlers can still be called, and fops_get() will
fail in try_module_get() and return a NULL pointer.
This change checks the fops_get() return value and returns -ENODEV if NULL.

As Randy Dunlap <randy.dunlap@oracle.com> reported, cx88 has some compilation issues:
drivers/built-in.o: In function `cx88_call_i2c_clients':
(.text+0x20af17): undefined reference to `videobuf_dvb_get_frontend'
drivers/built-in.o: In function `cx8802_probe':
cx88-mpeg.c:(.devinit.text+0x268c4): undefined reference to `videobuf_dvb_alloc_frontend'
cx88-mpeg.c:(.devinit.text+0x268ea): undefined reference to `videobuf_dvb_dealloc_frontends'
With those configs:
CONFIG_VIDEO_CX88=y
CONFIG_VIDEO_CX88_BLACKBIRD=y
CONFIG_VIDEO_CX88_DVB=m
CONFIG_DVB_CORE=m
After carefully examining the code, with the current code, several cx88 drivers
(cx8800, cx8802, cx88_dvb and cx88_blackbird) should be compiled as a module,
if one of them is marked as such. Just fixing Kconfig could create a very complex
set of rules. Also, this hides a problem with the current approach where the dvb
functionality weren't confined inside dvb module.
What happens is that:
- cx88-i2c (part of cx8800) has some special rules if DVB;
- cx88-mpeg (cx8802 module) has also part of DVB init code;
- cx88-dvb has the rest of the dvb code;
- cx88-blackbird can be used with cx88-mpeg, having cx88-dvb or not.
So, instead of doing some tricks at Kconfig and wait for a next breakage,
this patch moves the dvb code inside cx88-i2c and cx88-mpeg into cx88-dvb.
Another problem is that cx8802 were being compiled, even without cx88-dvb
and cx88-blackbird modules.
While on this code, let's fix also a reported problem:
http://www.linuxtv.org/pipermail/linux-dvb/2009-January/031225.html
A solution for the issue were proposed here:
http://www.mail-archive.com/linux-media@vger.kernel.org/msg00021.html
Thanks to Randy, Andy, Gregoire and Thomas for helping us to detect
and solve the issues.

The change that introduced it follows. The first part of the change,
with the 2 "static"s is the problem. The second part of the change,
for
older kernels is correct. Remove the duplicate static keyword and the
