From: Yinghai Lu Date: Sat, 21 Jan 2012 10:08:29 +0000 (-0800) Subject: PCI: Rename dev_res_x to add_res or fail_res X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=b9b0bba96cf5acbf025f7829fbf6c09e74323b41;p=mv-sheeva.git PCI: Rename dev_res_x to add_res or fail_res Linus says don't use dev_res_x because it doesn't communicate anything about usage. Rename them to add_res or fail_res etc according to context.
