Subject: [PATCH 4.9 16/44] Revert "PCI: Add ACS quirk for Intel 300 series"
Date: Thu, 27 Sep 2018 11:04:05 +0200 [thread overview]
Message-ID: <20180927090120.128021337@linuxfoundation.org> (raw)
In-Reply-To: <20180927090117.997362691@linuxfoundation.org>
4.9-stable review patch. If anyone has any objections, please let me know.
------------------
From: Mika Westerberg <mika.westerberg@linux.intel.com>
commit 50ca031b51106b1b46162d4e9ecccb7edc95682f upstream.
This reverts f154a718e6cc ("PCI: Add ACS quirk for Intel 300 series").
It turns out that erratum "PCH PCIe* Controller Root Port (ACSCTLR) Appear
As Read Only" has been fixed in 300 series chipsets, even though the
datasheet [1] claims otherwise. To make ACS work properly on 300 series
root ports, revert the faulty commit.
