This patchset is part of the effort led by Arnd Bergmann to clean up warnings in the kernel. This and following patchsets will focus on "-Wunused-but-set-variable" as it among the noisier ones. These were found compiling with W=1.

Changes in v2:
- Made the following changes suggested by Arnd in all 3 patches
  1. Each patch has a unique subject line.
  2. Add the commit that introduced/led to the warning with the "Fixes:" line.
  3. cc linux-wireles, cc commit authors.
