From c5cbc78acf693f5605d4a85b1327fa7933daf092 Mon Sep 17 00:00:00 2001 From: Nathan Chancellor <natechancellor@gmail.com> Date: Fri, 8 Mar 2019 11:37:44 -0700 Subject: [PATCH] tty: serial: qcom_geni_serial: Initialize baud in qcom_geni_console_setup When building with -Wsometimes-uninitialized, Clang warns: drivers/tty/serial/qcom_geni_serial.c:1079:6: warning: variable 'baud' is used uninitialized whenever 'if' condition is false [-Wsometimes-uninitialized] It's not wrong; when options is NULL, baud has no default value. Use 9600 as that is a sane default.
