From afcd609e8e7907ccfa04fef0a3adb7d60a298ed6 Mon Sep 17 00:00:00 2001 From: Colin Ian King Date: Wed, 31 Jul 2019 23:22:14 +0100 Subject: scsi: pm80xx: remove redundant assignments to variable rc There are several occasions where variable rc is being initialized with a value that is never read and error is being re-assigned a little later on. Clean up the code by removing rc entirely and just returning the return value from the call to pm8001_issue_ssp_tmf Addresses-Coverity: ("Unused value") Signed-off-by: Colin Ian King Acked-by: Jack Wang Signed-off-by: Martin K.
