Subject: [PATCH] leds: trigger: remove redundant assignment to variable ret

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

The variable ret is being assigned with a value that is never read
and it is being updated later with a new value. The initialization is
redundant and can be removed.

Addresses-Coverity: ("Unused value")
