Subject: [PATCH 4.8 28/35] pwm: Fix device reference leak
Date: Wed, 7 Dec 2016 08:08:44 +0100 [thread overview]
Message-ID: <20161207070723.826816630@linuxfoundation.org> (raw)
In-Reply-To: <20161207070722.410336250@linuxfoundation.org>
4.8-stable review patch. If anyone has any objections, please let me know.
------------------
From: Johan Hovold <johan@kernel.org>
commit 0e1614ac84f1719d87bed577963bb8140d0c9ce8 upstream.
Make sure to drop the reference to the parent device taken by
class_find_device() after "unexporting" any children when deregistering
a PWM chip.
Fixes: 0733424c9ba9 ("pwm: Unexport children before chip removal")
