From 413c2a110d649a3a313ee91920e3d9373b9f2045 Mon Sep 17 00:00:00 2001 From: Thierry Reding Date: Mon, 20 Jan 2020 15:22:37 +0100 Subject: pwm: sun4i: Initialize variables before use GCC can't always determine that the duty, period and prescaler values are initialized when returning from sun4i_pwm_calculate(), so help out a little by initializing them to 0.
