+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.
+
+Addresses-Coverity: ("Unused value")
