There is a block that is indented too deeply, remove
the extraneous tabs.

According the documentation for snd_soc_update_bits the API
will return a 1 if the update was successful with a value change,
a 0 if the update was successful with no value change or a negative
if the command just failed.
So the value of return in the driver needs to be checked for being less
then 0 or the caller may indicate failure when the value actually
changed.

Remove the unneeded and incorrect read of the TDM_CFG3 register.
The read is done but the value is never used.

sound/soc/codecs/tas2770.c:796:3-8: No need to set .owner here. The core will do it.
Remove .owner field if calls are used which set it automatically
