From bb9146688c0d48ca9f186fc7cd1d0ede6d8ff6c4 Mon Sep 17 00:00:00 2001 From: Jiri Slaby Date: Tue, 5 Jan 2021 13:02:37 +0100 Subject: [PATCH] tty: cpm_uart, use port->flags instead of low_latency 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.
