Uwe Kleine-König 85c25662d1 ALSA: hda: cs35l41: Make cs35l41_hda_remove() return void
Up to now cs35l41_hda_remove() returns zero unconditionally. Make it
return void instead which makes it easier to see in the callers that
there is no error to handle.

Also the return value of i2c and spi remove callbacks is ignored anyway.
