Subject: [PATCH][next] ALSA: echoaudio: remove redundant assignment to variable clock

The variable clock is being assigned a value that is never read,
it is being re-assigned a new value in every case in the following
switch statement. The assignment is redundant and can be removed.

Cleans up clang scan build warning:
sound/pci/echoaudio/echoaudio_3g.c:277:2: warning: Value stored
to 'clock' is never read [deadcode.DeadStores]
