      [media] DaVinci-VPFE-Capture: fix error handling · d3d83ee2
      Arnd Bergmann authored 
      A recent cleanup had the right idea to remove the initialization
of the error variable, but missed the actual benefit of that,
which is that we get warnings if there is a bug in it. Now
we get a warning about a bug that was introduced by this cleanup:

drivers/media/platform/davinci/vpfe_capture.c: In function 'vpfe_probe':
drivers/media/platform/davinci/vpfe_capture.c:1992:9: error: 'ret' may be used uninitialized in this function [-Werror=maybe-uninitialized]

This adds the missing initialization that the warning is about,
and another one that was preexisting and that we did not get
a warning for. That second bug has existed since the driver
was first added.

Fixes: efb74461 ("[media] DaVinci-VPFE-Capture: Delete an unnecessary variable initialisation in vpfe_probe()")
Fixes: 7da8a6cb ("V4L/DVB (12248): v4l: vpfe capture bridge driver for DM355 and DM6446")

      [media] cx88: make checkpatch.pl happy · 399426ca
      Mauro Carvalho Chehab authored 
      Usually, I don't like fixing coding style issues on non-staging
drivers, as it could be a mess pretty easy, and could become like
a snow ball. That's the case of recent changes on two changesets:
they disalign some statements. Yet, a care a lot with cx88 driver,
as it was the first driver I touched at the Kernel, and I've been
maintaining it since 2005. So, several of the coding style issues
were due to my code.

Per Andrey's suggestion, I ran checkpatch.pl in strict mode, with
fixed several other issues, did some function alinments, but broke
other alinments.

So, I had to manually apply another round of manual fixes to make
sure that everything is ok, and to make checkpatch happy with
this patch.

With this patch, checkpatch.pl is now happy when called with:
	./scripts/checkpatch.pl -f --max-line-length=998 --ignore PREFER_PR_LEVEL

Also, the 80-cols violations that made sense were fixed.

Checkpatch would be happier if we convert it to use dev_foo(),
but this is a more complex change.

NOTE: there are some places with msleep(1). As this driver was
written at the time that the default was to sleep at least 10ms
on such calls (e. g. CONFIG_HZ=100), I replaced those calls by
usleep_range(10000, 20000), with should be safe to avoid breakages.

Fixes: 65bc2fe8 ("[media] cx88: convert it to use pr_foo() macros")
Fixes: 7b61ba8f ("[media] cx88: make checkpatch happier")

      [media] v4l: rcar_fdp1: add FCP dependency · 1d389714
      Arnd Bergmann authored 
      Commit 4710b752 ("[media] v4l: Add Renesas R-Car FDP1 Driver") in the
v4l-dvb tree adds CONFIG_VIDEO_RENESAS_FDP1.

It calls into the FCP driver, but when there is no dependency, FCP might
be a module while FDP1 is built-in.

We have the same logic in VIDEO_RENESAS_VSP1, which also depends on
FCP not being a module when it is built-in itself.

drivers/media/platform/rcar_fdp1.o: In function `fdp1_pm_runtime_resume':
rcar_fdp1.c:(.text.fdp1_pm_runtime_resume+0x78): undefined reference to `rcar_fcp_enable'
drivers/media/platform/rcar_fdp1.o: In function `fdp1_pm_runtime_suspend':
rcar_fdp1.c:(.text.fdp1_pm_runtime_suspend+0x14): undefined reference to `rcar_fcp_disable'
drivers/media/platform/rcar_fdp1.o: In function `fdp1_probe':
rcar_fdp1.c:(.text.fdp1_probe+0x15c): undefined reference to `rcar_fcp_get'

      [media] v4l: rcar_fdp1: mark PM functions as __maybe_unused · fa4a2fd1
      Arnd Bergmann authored 
      The new driver produces a warning when CONFIG_PM is disabled:

platform/rcar_fdp1.c:2408:12: error: 'fdp1_pm_runtime_resume' defined but not used [-Werror=unused-function]
platform/rcar_fdp1.c:2399:12: error: 'fdp1_pm_runtime_suspend' defined but not used [-Werror=unused-function]

This marks the two functions as __maybe_unused.

      [media] dvb-net: split the logic at dvb_net_ule() into other functions · 8b0041db
      Mauro Carvalho Chehab authored 
      This function is too big and too complex, making really hard
to understand what's there.

Split it into sub-routines, in order to make it easier to be
understood, and to allow gcc to better parse it.

As a bonus, it gets rid of a goto in the middle of a routine.

      [media] dvb_net: prepare to split a very complex function · efb9ab67
      Mauro Carvalho Chehab authored 
      The dvb_net code has a really complex function, meant to handle
DVB network packages: it is long, has several loops and ifs
inside, and even cause warnings with gcc5.

Prepare it to be split into smaller functions by storing all
arguments and internal vars inside a struct.
