Subject: [PATCH AUTOSEL 4.14 28/28] iommu/vt-d: Fix the wrong printing in RHSA parsing
Date: Wed, 18 Mar 2020 16:55:55 -0400 [thread overview]
Message-ID: <20200318205555.17447-28-sashal@kernel.org> (raw)
In-Reply-To: <20200318205555.17447-1-sashal@kernel.org>
From: Zhenzhong Duan <zhenzhong.duan@gmail.com>
[ Upstream commit b0bb0c22c4db623f2e7b1a471596fbf1c22c6dc5 ]
When base address in RHSA structure doesn't match base address in
each DRHD structure, the base address in last DRHD is printed out.
This doesn't make sense when there are multiple DRHD units, fix it
by printing the buggy RHSA's base address.
