This removes build warning when COMPILE_TEST=y and MFD_STM32_TIMERS=n in drivers/pwm/pwm-stm32.c. In function 'stm32_pwm_capture' 'raw_prd' and 'raw_dty' may be used uninitialized in this function [-Wmaybe-uninitialized] Signed-off-by: Fabrice Gasnier <redacted>
Tested-by: Randy Dunlap <redacted> Thanks.
