Subject: [PATCH net 1/3] r8152: clear SELECTIVE_SUSPEND when autoresuming
Date: Wed, 29 Oct 2014 11:12:15 +0800	[thread overview]
Message-ID: <1394712342-15778-70-Taiwan-albertk@realtek.com> (raw)
In-Reply-To: <1394712342-15778-69-Taiwan-albertk@realtek.com>

The flag of SELECTIVE_SUSPEND should be cleared when autoresuming.
Otherwise, when the system suspend and resume occur, it may have
the wrong flow.

Besides, because the flag of SELECTIVE_SUSPEND couldn't be used
to check if the hw enables the relative feature, it should alwayes
be disabled in close().
