Subject: [PATCH 09/12] pps: fix device destruction ordering
Date: Fri, 14 Dec 2012 15:02:59 +0400 [thread overview]
Message-ID: <20121214110259.11019.63158.stgit@zurg> (raw)
In-Reply-To: <20121214110229.11019.63713.stgit@zurg>
device_destroy() calls final kfree(), thus cdev_del() must be called before it.
Catched as overwritten poison in kmalloc-512.
