Subject: [PATCH AUTOSEL 5.14 07/32] PCI: tegra194: Fix MSI-X programming
Date: Sat, 11 Sep 2021 09:11:24 -0400	[thread overview]
Message-ID: <20210911131149.284397-7-sashal@kernel.org> (raw)
In-Reply-To: <20210911131149.284397-1-sashal@kernel.org>

From: Om Prakash Singh <omp@nvidia.com>

[ Upstream commit 43537cf7e351264a1f05ed42ad402942bfc9140e ]

Lower order MSI-X address is programmed in MSIX_ADDR_MATCH_HIGH_OFF
DBI register instead of higher order address. This patch fixes this
programming mistake.
