From 7566655c9e659e890f44784a6403de98ad77ae5b Mon Sep 17 00:00:00 2001 From: Colin Ian King Date: Tue, 19 May 2020 16:45:53 +0100 Subject: [PATCH] w1_therm: remove redundant assignments to variable ret commit f37d13d52c0560bd2bac40b22466af538e61a5ce upstream. The variable ret is being initialized 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.
