Merge series "ASoC: Intel: atom: fix kernel-doc and W=1 warnings" from Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>:

Yet another series to fix broken kernel-doc and mark unused variables
as such.

Pierre-Louis Bossart (2):
  ASoC: Intel: atom: fix kernel-doc
  ASoC: Intel: atom: fix 'defined but not used' warning
