      [media] media/au0828: Fix IR stop, poll to not access device during disconnect · eb336eab
      由 Shuah Khan 提交于 
      au0828 IR stop and poll routines continue to access device
while usb disconnect is in progress. There is small window
between device disconnect and usb interface is set to null.
This results in filling the log with several of the following
error messages. Fix it to detect device disconnect condition
and avoid device access.

      [media] au0828: fix possible race condition in usage of dev->ctrlmsg · 77fc2863
      由 Devin Heitmueller 提交于 
      The register read function is referencing the dev->ctrlmsg structure outside
of the dev->mutex lock, which can cause corruption of the value if multiple
callers are invoking au0828_readreg() simultaneously.

Use a stack variable to hold the result, and copy the buffer returned by
usb_control_msg() to that variable.

In reality, the whole recv_control_msg() function can probably be collapsed
into au0288_readreg() since it is the only caller.

Also get rid of cmd_msg_dump() since the only case in which the function is
ever called only is ever passed a single byte for the response (and it is
already logged).

      [media] Stop using linux/version.h on most video drivers · 1990d50b
      由 Mauro Carvalho Chehab 提交于 
      All the modified drivers didn't have any version increment since
Jan, 1 2011. Several of them didn't have any version increment
for a long time, even having new features and important bug fixes
happening.

As we're now filling the QUERYCAP version with the current Kernel
Release, we don't need to maintain a per-driver version control
anymore. So, let's just use the default.

In order to preserve the Kernel module version history, a
KERNEL_VERSION() macro were added to all modified drivers, and
the extraver number were incremented.

I opted to preserve the per-driver version control to a few
pwc, pvrusb2, s2255, s5p-fimc and sh_vou.

A few drivers are still using the legacy way to handle ioctl's.
So, we can't do such change on them, otherwise, they'll break.
Those are: uvc, et61x251 and sn9c102.

The rationale is that the per-driver version control seems to be
actively maintained on those.

Yet, I think that the better for them would be to just use the
default version numbering, instead of doing that by themselves.

While here, removed a few uneeded include linux/version.h

      include cleanup: Update gfp.h and slab.h includes to prepare for breaking... · 5a0e3ad6
      由 Tejun Heo 提交于 
      include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h

percpu.h is included by sched.h and module.h and thus ends up being
included when building most .c files.  percpu.h includes slab.h which
in turn includes gfp.h making everything defined by the two files
universally available and complicating inclusion dependencies.

percpu.h -> slab.h dependency is about to be removed.  Prepare for
this change by updating users of gfp and slab facilities include those
headers directly instead of assuming availability.  As this conversion
needs to touch large number of source files, the following script is
used as the basis of conversion.

  http://userweb.kernel.org/~tj/misc/slabh-sweep.py

The script does the followings.

* Scan files for gfp and slab usages and update includes such that
  only the necessary includes are there.  ie. if only gfp is used,
  gfp.h, if slab is used, slab.h.

* When the script inserts a new include, it looks at the include
  blocks and try to put the new include such that its order conforms
  to its surrounding.  It's put in the include block which contains
  core kernel includes, in the same order that the rest are ordered -
  alphabetical, Christmas tree, rev-Xmas-tree or at the end if there
  doesn't seem to be any matching order.

* If the script can't find a place to put a new include (mostly
  because the file doesn't have fitting include block), it prints out
  an error message indicating which .h file needs to be added to the
  file.

The conversion was done in the following steps.

1. The initial automatic conversion of all .c files updated slightly
   over 4000 files, deleting around 700 includes and adding ~480 gfp.h
   and ~3000 slab.h inclusions.  The script emitted errors for ~400
   files.

2. Each error was manually checked.  Some didn't need the inclusion,
   some needed manual addition while adding it to implementation .h or
   embedding .c file was more appropriate for others.  This step added
   inclusions to around 150 files.

3. The script was run again and the output was compared to the edits
   from #2 to make sure no file was left behind.

4. Several build tests were done and a couple of problems were fixed.
   e.g. lib/decompress_*.c used malloc/free() wrappers around slab
   APIs requiring slab.h to be added manually.

5. The script was run on all .h files but without automatically
   editing them as sprinkling gfp.h and slab.h inclusions around .h
   files could easily lead to inclusion dependency hell.  Most gfp.h
   inclusion directives were ignored as stuff from gfp.h was usually
   wildly available and often used in preprocessor macros.  Each
   slab.h inclusion directive was examined and added manually as
   necessary.

6. percpu.h was updated not to include slab.h.

7. Build test were done on the following configurations and failures
   were fixed.  CONFIG_GCOV_KERNEL was turned off for all tests (as my
   distributed build env didn't work with gcov compiles) and a few
   more options had to be turned off depending on archs to make things
   build (like ipr on powerpc/64 which failed due to missing writeq).

   * x86 and x86_64 UP and SMP allmodconfig and a custom test config.
   * powerpc and powerpc64 SMP allmodconfig
   * sparc and sparc64 SMP allmodconfig
   * ia64 SMP allmodconfig
   * s390 SMP allmodconfig
   * alpha SMP allmodconfig
   * um on x86_64 SMP allmodconfig

8. percpu.h modifications were reverted so that it could be applied as
   a separate patch and serve as bisection point.

Given the fact that I had only a couple of failures from tests on step
6, I'm fairly confident about the coverage of this conversion patch.
If there is a breakage, it's likely to be something in one of the arch
headers which should be easily discoverable easily on most builds of
the specific arch.

      V4L/DVB (7750): au0828/ cleanups and fixes · b33d24c4
      由 Adrian Bunk 提交于 
      This patch contains the following cleanups and fixes:
- "debug" is definitely not a good name for a global variable,
  renamed it to "au0828_debug"
  this fixes a compile error with some kernel configurations
- since the module parameter is int the variable shouldn't be unsigned
- remove the {usb,bridge,i2c}_debug module parameters since they are
  already covered by the "debug" module parameter
- remove the unused au0828_bcount
- make the needlessly global i2c_scan static
- make the needlessly global dvb_register() static
