From 5c31252c4a86dc591c23f1a951edd52ad791ef0e Mon Sep 17 00:00:00 2001 From: Boris Brezillon Date: Wed, 1 Jul 2015 10:21:47 +0200 Subject: pwm: Add the pwm_is_enabled() helper Some PWM drivers are testing the PWMF_ENABLED flag. Create a helper function to hide the logic behind enabled test. This will allow us to smoothly move from the current approach to an atomic PWM update approach.
