ALSA: hda: cs35l41: Possible null pointer dereference in cs35l41_hda_unbind()
The cs35l41_hda_unbind() function clears the hda_component entry
matching it's index and then dereferences the codec pointer held in the
first element of the hda_component array, this is an issue when the
device index was 0.
Instead use the codec pointer stashed in the cs35l41_hda structure as it
will still be valid.
