Subject: [PATCH][next] lkdtm: remove redundant initialization of ret

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

The variable ret is being initialized with the value -EINVAL however
this value is never read and ret is being re-assigned later on. Hence
the initialization is redundant and can be removed.

Addresses-Coverity: ("Unused value")
