Merge series "ASoC: Intel: fix cppcheck warnings" from Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>:

This patchset tries to reduce the number of warnings on those drivers,
so that cppcheck can become a viable tool to detect issues (currently
hundreds of reports).

Most of the problems are related to unnecessary/redundant variable
assignments, prototypes and one nice logical mistake resulting in an
always-true condition.

Pierre-Louis Bossart (21):
  ASoC: Intel: Atom: sst-atom-controls: remove redundant assignments
  ASoC: Intel: Atom: compress: remove redundant assignment
  ASoC: Intel: Atom: platform-pcm: remove redundant assignment
  ASoC: Intel: Atom: sst: remove useless NULL assignment
  ASoC: Intel: Atom: remove redundant initialization
  ASoC: Intel: Atom: sst_pvt: remove redundant initialization
