Subject: [PATCH][next] ASoC: samsung: remove redundant pointer cpu_dai

From: Colin Ian King <colin.king@...onical.com>

The pointer cpu_dai is assigned a value but the pointer is never
read, hence it is redundant and can be removed.

Cleans up clang warning:
sound/soc/samsung/snow.c:45:2: warning: Value stored to 'cpu_dai' is never read
