From b26b2d494b659f988b4d75eb394dfa0ddac415c9 Mon Sep 17 00:00:00 2001 From: Dominik Brodowski Date: Fri, 1 Jan 2010 17:40:49 +0100 Subject: resource/PCI: align functions now return start of resource As suggested by Linus, align functions should return the start of a resource, not void. An update of "res->start" is no longer necessary.
