From: Nathan Chancellor Date: Fri, 8 Mar 2019 18:37:44 +0000 (-0700) Subject: tty: serial: qcom_geni_serial: Initialize baud in qcom_geni_console_setup X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=c5cbc78acf69;p=linux.git 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.
