Subject: [PATCH] scsi: pm80xx: remove redundant assignments to variable rc
Git-commit: afcd609e8e7907ccfa04fef0a3adb7d60a298ed6
Patch-Mainline: v5.4-rc1
References: bsc#1156419,jsc#SLE-8281

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")
