Subject: [PATCH] PCI:pciehp:remove unnecessary volatile in struct controller
Date: Sun, 13 Jul 2008 18:46:42 +0800 [thread overview]
Message-ID: <1215946002-4775-1-git-send-email-tom.leiming@gmail.com> (raw)
From: Ming Lei <tom.leiming@gmail.com>
Proper memory barriers have been added to order accesses
to ->cmd_busy, so volatile declaration for cmd_busy can
be removed.
