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")
