Subject: [PATCH 02/12] PCI/switchtec: Fix vep_vector_number ioread width
Date: Mon,  6 Jan 2020 12:03:27 -0700	[thread overview]
Message-ID: <20200106190337.2428-3-logang@deltatee.com> (raw)
In-Reply-To: <20200106190337.2428-1-logang@deltatee.com>

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")
Reported-by: Doug Meyer <dmeyer@gigaio.com>
Signed-off-by: Logan Gunthorpe <logang@deltatee.com>
