Merge series "ASoC: rt1015: apply some refactors" from Tzung-Bi Shih <tzungbi@google.com>:

The series refactors rt1015.c.

The 1st patch sorts header inclusions alphabetically.

The 2nd and 3rd patch improve error handling for kcontrols.

The 4th patch enhances readability.

The 5th patch removes unused variables in rt1015_priv.

Tzung-Bi Shih (5):
  ASoC: rt1015: sort header inclusions
  ASoC: rt1015: save boost_mode only if valid
  ASoC: rt1015: return error if any when setting bypass_boost
  ASoC: rt1015: refactor retry loop and rt1015_priv allocation
  ASoC: rt1015: remove unneeded variables in rt1015_priv
