Subject: [PATCH] mt7601u: Remove redundant initialization of variable ret

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

The variable ret is being initialized with a value that is never read,
it is assigned later on with a different value. The initialization is
redundant and can be removed.

Addresses-Coverity: ("Unused value")
