[PATCH v1 1/2] ALSA: hda: cs35l41: Do not allow uninitialised variables to be freed

[Stefan Binding]

Initialise the variables to NULL so that they cannot be uninitialised
when devm_kfree is called.

Found by static analysis.

Fixes: 8c4c216db8fb ("ALSA: hda: cs35l41: Add config table to support many laptops without _DSD")
