Subject: [PATCH 20/23] ASoC: tas2562: remove warning on return value

cppcheck warning:

sound/soc/codecs/tas2562.c:530:9: warning: Identical condition and return expression 'ret', return value is always 0 [identicalConditionAfterEarlyExit]
 return ret;
        ^
sound/soc/codecs/tas2562.c:525:6: note: If condition 'ret' is true, the function will return/exit
 if (ret)
     ^
sound/soc/codecs/tas2562.c:530:9: note: Returning identical expression 'ret'
 return ret;
        ^

Fix with return 0
