Subject: [PATCH] [media] radio-raremono: remove redundant initialization of freq

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

Variable freq is initialized to f->frequency however this value
is never read and freq is later updated; hence the initialization
is redundant and can be removed.

Cleans up clang warning:
drivers/media/radio/radio-raremono.c:257:6: warning: Value stored
to 'freq' during its initialization is never read
