Subject: [PATCH v4 08/52] PCI: Remove duplicated code for resource sorting
Date: Thu, 20 Aug 2015 23:20:23 -0700 [thread overview]
Message-ID: <1440138067-4314-9-git-send-email-yinghai@kernel.org> (raw)
In-Reply-To: <1440138067-4314-1-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, so
choose to keep sort_resources(), and remove related code in
pdev_sort_resources().
