From f85a299f5ec55c82403cd2bc4aeaaedebfcf5ef6 Mon Sep 17 00:00:00 2001 From: Bart Van Assche Date: Mon, 29 Jun 2020 15:54:53 -0700 Subject: [PATCH] scsi: qla2xxx: Make qla2x00_restart_isp() easier to read Instead of using complicated control flow to only have one return statement at the end of qla2x00_restart_isp(), return an error status as soon as it is known that this function will fail.
