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 <colin.king@canonical.com> Acked-by: Jack Wang <jinpu.wang@cloud.ionos.com> Signed-off-by: Martin K.
