Subject: [PATCH 6/6] ntb_hw_switchtec: Fix a minor issue in config_req_id_table()
Date: Thu, 23 Dec 2021 17:23:34 -0800 [thread overview]
Message-ID: <20211224012334.89173-7-kelvin.cao@microchip.com> (raw)
In-Reply-To: <20211224012334.89173-1-kelvin.cao@microchip.com>
The req_id_table_size field is 16-bit wide, use ioread16() to read the
value.
