Subject: [PATCH v2 1/3] pwm: ftm: fix one bug of wrong counting the use counter.
Date: Wed, 15 Oct 2014 13:21:33 +0800 [thread overview]
Message-ID: <1413350495-40980-2-git-send-email-Li.Xiubo@freescale.com> (raw)
In-Reply-To: <1413350495-40980-1-git-send-email-Li.Xiubo@freescale.com>
No matter what times the FTM pwm is enabled, the use_count will
always be one.
