[PATCH 5.0 081/146] tty: serial: qcom_geni_serial: Initialize baud in qcom_geni_console_setup

[Greg Kroah-Hartman]

5.0-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Nathan Chancellor <natechancellor@xxxxxxxxx>

commit c5cbc78acf693f5605d4a85b1327fa7933daf092 upstream.

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.
