Merge series "ASoC: remove cppchecks warnings on lm49453 and da732x" from Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>:

There are the last two patches in the cleanups, this time I am not
sure what the code does and what the proper fix might be. Feedback
welcome.

Pierre-Louis Bossart (2):
  ASoC: lm49453: fix useless assignment before return
  ASoC: da732x: simplify code
