Subject: [PATCH] power: supply: isp1704: 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
assignment is redundant and can be removed.

Addresses-Coverity: ("Unused value")
