Subject: [PATCH] Input: rpckbd - fix a leak of the IRQ during init failure
Date: Sun, 03 Apr 2011 09:41:06 +0800 [thread overview]
Message-ID: <1301794866.3657.1.camel@phoenix> (raw)
In rpckbd_open prror path, free_irq() was using NULL rather than the
driver data as the data pointer so free_irq() wouldn't have matched.
