From beca62c4212ade1516a526784adf7f7d99c7f3d9 Mon Sep 17 00:00:00 2001 From: Jason Yan Date: Wed, 6 May 2020 14:17:35 +0800 Subject: [PATCH] tty: mxser: make mxser_change_speed() return void No other functions use the return value of mxser_change_speed() and the return value is always 0 now. Make it return void. This fixes the following coccicheck warning: drivers/tty/mxser.c:645:5-8: Unneeded variable: "ret".
