Hi Lee,

After merging the mfd tree, today's linux-next build (powerpc
allyesconfig) produced this warning:

drivers/pwm/pwm-stm32.c: In function 'stm32_pwm_apply':
drivers/pwm/pwm-stm32.c:204:33: warning: 'curstate.polarity' may be used uninitialized in this function [-Wmaybe-uninitialized]
  if (state->polarity != curstate.polarity)
                                 ^

Introduced by commit

  bafffb6e7bd1 ("pwm: Add driver for STM32 plaftorm")
