Subject: [PATCH 3.14 43/46] PCI: Mark Atheros AR9485 and QCA9882 to avoid bus reset
Date: Thu, 18 Aug 2016 15:55:05 +0200	[thread overview]
Message-ID: <20160818135448.871024496@linuxfoundation.org> (raw)
In-Reply-To: <20160818135442.457400364@linuxfoundation.org>

3.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Chris Blake <chrisrblake93@gmail.com>

commit 9ac0108c2bac3f1d0255f64fb89fc27e71131b24 upstream.

Similar to the AR93xx series, the AR94xx and the Qualcomm QCA988x also have
the same quirk for the Bus Reset.
