Subject: [PATCH 5/7] usbnet: smsc95xx: don't recover device if suspend fails in system sleep
Date: Tue, 5 Mar 2013 12:01:41 +0800 [thread overview]
Message-ID: <1362456103-24956-6-git-send-email-ming.lei@canonical.com> (raw)
In-Reply-To: <1362456103-24956-1-git-send-email-ming.lei@canonical.com>
If suspend callback fails in system sleep context, usb core will
ignore the failure and let system sleep go ahead further, so
this patch doesn't recover device under this situation.
