Subject: [PATCH 09/15] pinctrl: pinctrl-nomadik: Fix possible memory leak
Date: Wed, 20 Jun 2012 13:56:45 +0100	[thread overview]
Message-ID: <1340197011-5435-10-git-send-email-lee.jones@linaro.org> (raw)
In-Reply-To: <1340197011-5435-1-git-send-email-lee.jones@linaro.org>

If the Nomadik Pin Control driver is continuously bound and unbound
from the same device a number of times the kzalloc() will leak
memory. Replacing it with devm_kzalloc() will ensure memory is
freed automatically in the event of failure and unbinding.
