Subject: [PATCH 10/12] tty: cpm_uart, use port->flags instead of low_latency
Date: Tue,  5 Jan 2021 13:02:37 +0100	[thread overview]
Message-ID: <20210105120239.28031-10-jslaby@suse.cz> (raw)
In-Reply-To: <20210105120239.28031-1-jslaby@suse.cz>

This is the only in-kernel user of tty_port::low_latency. Switch this
last one to test uport->flags directly as tty_port::low_latency is going
away in the next patch.
