Subject: [PATCH] watchdog: da9055: Fix invalid free of devm_ allocated data
Date: Fri, 21 Dec 2012 21:09:06 +0800	[thread overview]
Message-ID: <1356095346.18328.0.camel@phoenix> (raw)

It is not required to free devm_ allocated data. Since kref_put
needs a valid release function, da9055_wdt_release_resources()
is not deleted.
