Subject: [PATCH 2/2] pwm: stm32: initialize raw local variables
Date: Fri, 18 May 2018 17:24:04 +0200	[thread overview]
Message-ID: <1526657044-14879-3-git-send-email-fabrice.gasnier@st.com> (raw)
In-Reply-To: <1526657044-14879-1-git-send-email-fabrice.gasnier@st.com>

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]
