[PATCH 8/8] ASoC: rockchip: i2s_tdm: improve return value handling

[Pierre-Louis Bossart <pierre-louis.bossart@xxxxxxxxxxxxxxx>]

cppcheck reports the following warning:

sound/soc/rockchip/rockchip_i2s_tdm.c:599:9: warning: Identical
condition and return expression 'ret', return value is always 0
[identicalConditionAfterEarlyExit]

 return ret;
        ^
sound/soc/rockchip/rockchip_i2s_tdm.c:594:6: note: If condition 'ret'
is true, the function will return/exit
 if (ret)
     ^
sound/soc/rockchip/rockchip_i2s_tdm.c:599:9: note: Returning identical
expression 'ret'

 return ret;
        ^

While the code is not wrong, it's clearer to return 0 directly.
