Subject: [PATCH v8 31/61] PCI: Remove duplicated code for resource sorting
Date: Tue, 27 Oct 2015 13:55:23 -0700 [thread overview]
Message-ID: <1445979353-1728-32-git-send-email-yinghai@kernel.org> (raw)
In-Reply-To: <1445979353-1728-1-git-send-email-yinghai@kernel.org>
Now sort_resources() and pdev_sort_resources() all have sorting
code.
As we are going to call sort_resources() several places later for
alt_size support, so choose to remove related code in
pdev_sort_resources().
