aw88261_reg_update() returns an unintialized error code in the success path:
sound/soc/codecs/aw88261.c:651:7: error: variable 'ret' is used uninitialized whenever 'if' condition is false [-Werror,-Wsometimes-uninitialized] if (aw_dev->prof_cur != aw_dev->prof_index) { ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ sound/soc/codecs/aw88261.c:660:9: note: uninitialized use occurs here return ret; ^~~ sound/soc/codecs/aw88261.c:651:3: note: remove the 'if' if its condition is always true if (aw_dev->prof_cur != aw_dev->prof_index) { ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Return zero instead here.
