Subject: [PATCH AUTOSEL 4.14 17/22] nvme-pci: Use single IRQ vector for old Apple models
Date: Mon,  2 Mar 2020 21:49:28 -0500	[thread overview]
Message-ID: <20200303024933.10371-17-sashal@kernel.org> (raw)
In-Reply-To: <20200303024933.10371-1-sashal@kernel.org>

From: Andy Shevchenko <andriy.shevchenko@linux.intel.com>

[ Upstream commit 98f7b86a0becc1154b1a6df6e75c9695dfd87e0d ]

People reported that old Apple machines are not working properly
if the non-first IRQ vector is in use.

Set quirk for that models to limit IRQ to use first vector only.

Based on original patch by GitHub user npx001.
