[alsa-devel] [PATCH] ALSA: cs4281: remove redundant assignment to variable val and remove a goto

[Colin King]

From: Colin Ian King <colin.king at canonical.com>

The variable val is being assigned with a value that is never
read and it is being updated later with a new value. The
assignment is redundant and can be removed.  Also remove a
goto statement and a label and replace with a break statement.

Addresses-Coverity: ("Unused value")
