Date: Sat, 19 Oct 2013 01:49:38 +0400 From: Alexey Khoroshilov <khoroshilov@...ras.ru> To: Greg Kroah-Hartman <gregkh@...uxfoundation.org> Cc: Alexey Khoroshilov <khoroshilov@...ras.ru>, linux-usb@...r.kernel.org, linux-kernel@...r.kernel.org, ldv-project@...uxtesting.org Subject: [PATCH] USB: wusbcore: fix usb_dev leaks cbaf_probe() does cbaf->usb_dev = usb_get_dev(interface_to_usbdev(iface)), but there is no usb_put_dev() anywhere in cbaf. The patch adds usb_put_dev() to cbaf_disconnect() and to an error path in cbaf_probe(). Also it adds missed usb_put_intf(iface) to the error path. Found by Linux Driver Verification project (linuxtesting.org).
