Subject: [PATCH 3/8] serial: 8250: Copy em485 from port to real port.
Date: Fri,  1 Jun 2018 14:40:16 +0200	[thread overview]
Message-ID: <20180601124021.102970-4-giulio.benetti@micronovasrl.com> (raw)
In-Reply-To: <20180601124021.102970-1-giulio.benetti@micronovasrl.com>

em485 gets lost during serial8250_register_8250_port().

Copy em485 to final uart port.
