[PATCH] ASoC: codecs: pcm6240: Return 0 explicitly on success

[phucduc.bui@gmail.com]

From: bui duc phuc <phucduc.bui@gmail.com>

The return value of pcmdev_dev_read() is already checked, and
errors are returned immediately. Therefore, the remaining paths
are successful paths and should return 0 explicitly instead of
returning ret.
