Subject: [PATCH 07/36] PCI: Remove duplicated code for resource sorting
Date: Mon, 6 Jul 2015 16:38:57 -0700 [thread overview]
Message-ID: <1436225966-27247-8-git-send-email-yinghai@kernel.org> (raw)
In-Reply-To: <1436225966-27247-1-git-send-email-yinghai@kernel.org>
Now __sort_resources, and pdev_sort_resources all have sorting
code.
We can use __sort_resources calling and remove related code in
pdev_sort_resources.
As we are going to call __sort_resources several places, so choose to
keep __sort_resources instead.
