Date: Fri, 7 Sep 2012 10:33:07 +0800 From: Huang Shijie <b32955@...escale.com> To: <gregkh@...uxfoundation.org> CC: <alan@...ux.intel.com>, <linux-serial@...r.kernel.org>, <linux-arm-kernel@...ts.infradead.org>, <linux-kernel@...r.kernel.org>, <shawn.guo@...aro.org>, Huang Shijie <b32955@...escale.com> Subject: [PATCH] serial: mxs-auart: put the device when exit or error We call the get_device() in the mxs_auart_probe(). For the balance of the reference count, we should put the device in the mxs_auart_remove() or in the error path of probe.
