   8 commit c5cbc78acf693f5605d4a85b1327fa7933daf092 upstream.
   9
  10 When building with -Wsometimes-uninitialized, Clang warns:
  11
  12 drivers/tty/serial/qcom_geni_serial.c:1079:6: warning: variable 'baud'
  13 is used uninitialized whenever 'if' condition is false
  14 [-Wsometimes-uninitialized]
  15
  16 It's not wrong; when options is NULL, baud has no default value. Use
  17 9600 as that is a sane default.
