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") -- Cheers, Stephen Rothwell
