Subject: [PATCH] pwm: sysfs: get return value from pwm_apply_state()
Date: Wed, 8 Jun 2016 10:58:23 +0900	[thread overview]
Message-ID: <1465351103-3152-1-git-send-email-yoshihiro.shimoda.uh@renesas.com> (raw)

From: Ryo Kodama <ryo.kodama.vz@renesas.com>

This patch adds to check the return value from pwm_apply_state()
used in enable_store(). The error of enable_store() doesn't work
if the return value doesn't received.
