[PATCH v3 0/13] drivers/video: W=1 warning fixes

[Sam Ravnborg]

Following the great work of Lee Jones in other subsystems
here is a set of patches that address all remaining W=1
warnings in drivers/video/.
Lee Jones already fixed all warnings in video/backlight/ so
this is mostly fbdev related fixes.

The general approach used were:
- Fix kernel-doc, this is often very trivial
- Drop unused local variables

Build tested on a set of architectures with various configs.

The patches do not depend on each other and fixes for one driver
are kept in a single patch.

v2:
  - Updated subject of the patches to tell what was fixed (Lee)
  - Fixed build error in one patch (kernel test robot)
  - A few editorials updates to the changelog messages

v3:
  - Applied patches that was acked - thanks Thomas!
  - Updated patches after feedback from Randy and Thomas
  - Added several new patches to cover warnings that triggers
    with other architectures than the one I used for v1 + v2
  - Included one sh specific fix that handle a corner-case,
    let's see what the sh people say to that
  - One fix to previous set of patches to fix an issue
    reported by Coverity (By Colin)
