Subject: [PATCH 09/21] PCI: Move pdev_sort_resources() to setup-bus.c
Date: Sat, 21 Jan 2012 02:08:25 -0800 [thread overview]
Message-ID: <1327140517-14811-10-git-send-email-yinghai@kernel.org> (raw)
In-Reply-To: <1327140517-14811-1-git-send-email-yinghai@kernel.org>
So we could move definition of struct resource_list to setup_bus.c
later could convert resource_list to regular list.
Suggested-by: Linus Torvalds <torvalds@linux-foundation.org>
