[PATCH][next] pstore/zone: remove redundant initializations to variable ret

From: Colin King
Date: Tue May 12 2020 - 13:38:06 EST


From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

The variable rc 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. In one of the cases, ret can also be moved inside a
for-loop to reduce the scope.

Addresses-Coverity: ("Unused value")
