Subject: [PATCH AUTOSEL 5.5 058/542] PCI/switchtec: Fix vep_vector_number ioread width
Date: Fri, 14 Feb 2020 10:40:50 -0500 [thread overview]
Message-ID: <20200214154854.6746-58-sashal@kernel.org> (raw)
In-Reply-To: <20200214154854.6746-1-sashal@kernel.org>
From: Logan Gunthorpe <logang@deltatee.com>
[ Upstream commit 9375646b4cf03aee81bc6c305aa18cc80b682796 ]
vep_vector_number is actually a 16 bit register which should be read with
ioread16() instead of ioread32().
Fixes: 080b47def5e5 ("MicroSemi Switchtec management interface driver")
