From b4d4dc33a372aaee2205d4506b4c7ead6275067d Mon Sep 17 00:00:00 2001 From: Dan Williams Date: Fri, 22 Jun 2012 11:31:14 -0700 Subject: isci: fix isci_pci_probe() generates warning on efi failure path commit 6d70a74ffd616073a68ae0974d98819bfa8e6da6 upstream. The oem parameter image embedded in the efi variable is at an offset from the start of the variable. However, in the failure path we try to free the 'orom' pointer which is only valid when the paramaters are being read from the legacy option-rom space. Since failure to load the oem parameters is unlikely and we keep the memory around in the success case just defer all de-allocation to devm.
