b399c46ea0 Merge branch 'v4l_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media
Pull media updates from Mauro Carvalho Chehab:
 - a new jpeg codec driver for Samsung Exynos (jpeg-hw-exynos4)
 - a new dvb frontend for ds2103 chipset (m88ds2103)
 - a new sensor driver for Samsung S5K5BAF UXGA (s5k5baf)
 - new drivers for R-Car VSP1
 - a new radio driver: radio-raremono
 - a new tuner driver for ts2022 chipset (m88ts2022)
 - the analog part of em28xx is now a separate module that only
   load/runs if the device is not a pure digital TV device
 - added a staging driver for bcm2048 radio devices
 - the omap 2 video driver (omap24xx) was moved to staging.  This driver
   is for an old hardware and uses a deprecated Kernel internal API.  If
   nobody cares enough to fix it, it would be removed on a couple Kernel
   releases
 - the sn9c102 driver was moved to staging.  This driver was replaced by
   gspca, and disabled on some distros, as almost all devices are known
   to work properly with gspca.  It should be removed from kernel on a
   couple Kernel releases
 - lots of driver fixes, improvements and cleanups

f7d40eea8e [media] v4l: omap4iss: Restore irq flags correctly in omap4iss_video_buffer_next()
The spin_lock_irqsave() macro is not nestable.  The second call will
overwrite the first record of "flags" so the IRQs will not be enabled
correctly at the end of the function.

In the current code, this function is always called from the IRQ handler
so everything works fine and this fix doesn't change anything.

The sd->name buffer can only hold 32 characters.  I've changed it to use
snprintf() to silence the overflow warning.

Also I have removed the call to strlcpy() which is a no-op.

a03636cb21 [media] omap24xx/tcm825x: move to staging for future removal
The omap24xx driver and the tcm825x sensor driver are the only two
remaining drivers to still use the old deprecated v4l2-int-device API.

Nobody maintains these drivers anymore. But unfortunately the v4l2-int-device
API is used by out-of-tree drivers (MXC platform). This is a very bad situation
since as long as this deprecated API stays in the kernel there is no reason for
those out-of-tree drivers to convert.

This patch moves v4l2-int-device and the two drivers that depend on it to
staging in preparation for their removal.

If someone would be interested in getting these drivers to work, then start with
this since it's not very far from the state where they used to work:

<URL:http://vihersipuli.retiisi.org.uk/cgi-bin/gitweb.cgi?p=~sailus/linux-omap/.git;a=summary>

The branch is n800-cam. Porting to up-to-date APIs can then be done. David
might have done some work in that area, so check with him first.

b8da9d3aaf [media] sn9c102: prepare for removal by moving it to staging
During the last media summit meeting it was decided to move this driver to
staging as the first step to removing it altogether.

Most webcams covered by this driver are now supported by gspca. Nobody has the
hardware to convert the remaining devices to gspca.

This driver needs a major overhaul to have it conform to the latest frameworks
and compliancy tests.

Without hardware, however, this is next to impossible. Given the fact that
this driver seems to be pretty much unused (it has been removed from Fedora
several versions ago and nobody complained about that), we decided to drop
this driver.

This patch moves it to staging. Some time in 2014 we will drop it completely.

None of these files are actually using any __init type directives
and hence don't need to include <linux/init.h>.  Most are just a
left over from __devinit and __cpuinit removal, or simply due to
code getting copied from one driver to the next.

112da08512 [media] v4l: omap4iss: Cancel streaming when a fatal error occurs
When a fatal error that prevents any further video streaming occurs in a
pipeline, all queued buffers must be marked as erroneous and new buffers
must be prevented from being queued. Implement this behaviour with a new
omap4iss_pipeline_cancel_stream() function that can be used by
submodules to cancel streaming.

f3632ba850 [media] v4l: omap4iss: Reset the ISS when the pipeline can't be stopped
When a failure to stop a module in the pipeline is detected, the only
way to recover is to reset the ISS. However, as other users can be using
a different pipeline with other modules, the ISS can't be reset
synchronously with the error detection.
Keep track of modules that have failed to stop, and reset the ISS
accordingly when the last user releases the last reference to the ISS.
Refuse to start streaming on a pipeline that contains a crashed module,
as the hardware wouldn't work anyway.
Modify the omap4iss_pipeline_set_stream() function to record the new ISS
pipeline state only when no error occurs, except when stopping the
pipeline in which case the pipeline is still marked as stopped.
