pwm: stm32: Initialize raw local variables
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 <fabrice.gasnier@st.com> Acked-by: Thierry Reding <thierry.reding@gmail.com> Tested-by: Randy Dunlap <rdunlap@infradead.org> Signed-off-by: Lee Jones <lee.jones@linaro.org>
