Pull media updates from Mauro Carvalho Chehab:
 "The main set of series of patches for media subsystem, including:
   - document RC sysfs class
   - added an API to setup scancode to allow waking up systems using the
     Remote Controller
   - add API for SDR devices.  Drivers are still on staging
   - some API improvements for getting EDID data from media
     inputs/outputs
   - new DVB frontend driver for drx-j (ATSC)
   - one driver (it913x/it9137) got removed, in favor of an improvement
     on another driver (af9035)
   - added a skeleton V4L2 PCI driver at documentation
   - added a dual flash driver (lm3646)

   - some improvements at the usbtv driver, to allow its core to be
     reused.
   - added a new SDR driver (rtl2832u_sdr)
   - added a new tuner driver (msi001)
   - several improvements at em28xx driver to fix PM support, device
     removal and to split the V4L2 specific bits into a separate
     sub-driver
   - one driver got converted to videobuf2 (s2255drv)
   - the e4000 tuner driver now follows an improved binding model
   - some fixes at V4L2 compat32 code
   - several fixes and enhancements at videobuf2 code
   - some cleanups at V4L2 API documentation
   - usual driver enhancements, new board additions and misc fixups"

[ NOTE! This merge effective drops commit 4329b93b28 ("of: Reduce
  indentation in of_graph_get_next_endpoint").

  The of_graph_get_next_endpoint() function was moved and renamed by
  commit fd9fdb78a9 ("[media] of: move graph helpers from
  drivers/media/v4l2-core to drivers/of").  It was originally called
  v4l2_of_get_next_endpoint() and lived in the file
  drivers/media/v4l2-core/v4l2-of.c.

  In that original location, it was then fixed to support empty port
  nodes by commit b9db140c1e ("[media] v4l: of: Support empty port
  nodes"), and that commit clashes badly with the dropped "Reduce
  intendation" commit.  I had to choose one or the other, and decided
  that the "Support empty port nodes" commit was more important ]

9b3c6e85c2 Drivers: edac: remove __dev* attributes.
CONFIG_HOTPLUG is going away as an option.  As a result, the __dev*
markings need to be removed.

This change removes the use of __devinit, __devexit_p, and __devexit
from these drivers.

Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.

9eb07a7fb8 edac: edac_mc_handle_error(): add an error_count parameter
In order to avoid loosing error events, it is desirable to group
error events together and generate a single trace for several identical
errors.

The trace API already allows reporting multiple errors. Change the
handle_error function to also allow that.

The changes at the drivers were made by this small script:

	$file .=$_ while (<>);
	$file =~ s/(edac_mc_handle_error)\s*\(([^\,]+)\,([^\,]+)\,/$1($2,$3, 1,/g;
	print $file;

03f7eae80f edac: remove arch-specific parameter for the error handler
Remove the arch-dependent parameter, as it were not used,
as the MCE tracepoint weren't implemented. It probably doesn't
make sense to have an MCE-specific tracepoint, as this will
cost more bytes at the tracepoint, and tracepoint is not free.

The changes at the EDAC drivers were done by this small perl script:

	$file .=$_ while (<>);
	$file =~ s/(edac_mc_handle_error)\s*\(([^\;]+)\,([^\,\)]+)\s*\)/$1($2)/g;

dd23cd6eb1 edac: Don't add __func__ or __FILE__ for debugf[0-9] msgs

$f =~ s/(debugf[0-9]\s*\(\")\%s[\:\,\(\)]*\s*([^\"]*\s*[^\)]+),\s*__func__\s*\)/\1\2)/g;
$f =~ s/(debugf[0-9]\s*\(\"MC\:\s*)\%s[\:\,\(\)]*\s*([^\"]*\s*[^\)]+)__func__\s*\,\s*/\1\2/g;
$f =~ s/(debugf[0-9]\s*\(\"MC\:\s*)\%s[\:\,\(\)]*\s*([^\"]*\s*[^\)]+),\s*__func__\s*\)/\1\2)/g;

$f =~ s/\"MC\: \\n\"/"MC:\\n"/g;

print $f;

After running the script, manual cleanups were done to fix it the remaining
places.

While here, removed the __LINE__ on most places, as it doesn't actually give
useful info on most places.

de3910eb79 edac: change the mem allocation scheme to make Documentation/kobject.txt happy
Kernel kobjects have rigid rules: each container object should be
dynamically allocated, and can't be allocated into a single kmalloc.

EDAC never obeyed this rule: it has a single malloc function that
allocates all needed data into a single kzalloc.

As this is not accepted anymore, change the allocation schema of the
EDAC *_info structs to enforce this Kernel standard.

5e2af0c09e edac: Don't initialize csrow's first_page & friends when not needed
Almost all edac	drivers	initialize csrow_info->first_page,
csrow_info->last_page and csrow_info->page_mask. Those vars are
used inside the EDAC core, in order to calculate the csrow affected
by an error, by using the routine edac_mc_find_csrow_by_page().

However, very few drivers actually use it:
        e752x_edac.c
        e7xxx_edac.c
        i3000_edac.c
        i82443bxgx_edac.c
        i82860_edac.c
        i82875p_edac.c
        i82975x_edac.c
        r82600_edac.c

There also a few other drivers that have their own calculus
formula internally using those vars.

All the others are just wasting time by initializing those
data.

While initializing data without using them won't cause any troubles, as
those information is stored at the wrong place (at csrows structure), it
is better to remove what is unused, in order to simplify the next patch.

084a4fccef edac: move dimm properties to struct dimm_info
On systems based on chip select rows, all channels need to use memories
with the same properties, otherwise the memories on channels A and B
won't be recognized.

However, such assumption is not true for all types of memory
controllers.

Controllers for FB-DIMM's don't have such requirements.

Also, modern Intel controllers seem to be capable of handling such
differences.

So, we need to get rid of storing the DIMM information into a per-csrow
data, storing it, instead at the right place.

The first step is to move grain, mtype, dtype and edac_mode to the
per-dimm struct.

0142877aa4 i5400_edac: Avoid calling pci_put_device() twice
When i5400_edac driver is removed and re-loaded a few times, it causes
an OOPS, as it is currently decrementing some PCI device usage two
times.

When called inside a loop, pci_get_device() will call
pci_put_device(). That mangles the error count. In this specific
case, it seems easier to just duplicate the call.

Also fixes the error logic when pci_get_device fails.

b425d5c82d edac: i5400: improve handling of pci_enable_device() return value
-EIO is not the only error code that pci_enable_device() may return, also
the set of errors can be enhanced in future.  We should compare return
code with zero, not with concrete error value.

156edd4aaa edac: i5400 fix csrow mapping
The i5400 EDAC driver has several bugs with chip-select row computation
which most likely lead to bugs in detailed error reporting.  Attempts to
contact the authors have gone mostly unanswered so I am presenting my diff
here.  I do not subscribe to lkml and would appreciate being kept in the
cc.

The most egregious problem was miscalculating the addresses of MTR
registers after register 0 by assuming they are 32bit rather than 16.
This caused the driver to miss half of the memories.  Most motherboards
tend to have only 8 dimm slots and not 16, so this may not have been
noticed before.

Further, the row calculations multiplied the number of dimms several
times, ultimately ending up with a maximum row of 32.  The chipset only
supports 4 dimms in each of 4 channels, so csrow could not be higher than
4 unless you use a row per-rank with dual-rank dimms.  I opted to
eliminate this behavior as it is confusing to the user and the error
reporting works by slot and not rank.  This gives a much clearer view of
memory by slot and channel in /sys.
