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