Subject: [PATCH] [media] variable name is never null, so remove null check

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

The variable name is always assigned to a literal string in the
proceeding switch statement, so it is never null and hence the
null check is redundant. Remove null the check.
