Message-ID: <4996C549.4040209@gmail.com> Date: Sat, 14 Feb 2009 21:21:13 +0800 From: Dave Young <hidave.darkstar@...il.com> To: gregkh@...e.de CC: linux-usb@...r.kernel.org, linux-kernel@...r.kernel.org Subject: [PATCH 1/2] usb-serial: fix usb_serial_register bug when boot with nousb param (v2) With "nousb" cmdline booting, built-in serial drivers (ie. airecable) will trigger kernel oops. Indeed, if nousb, usb_serial_init will failed, and the usb serial bus type will not be registerd, then usb_serial_register call driver_register which try to register the driver to a not registered bus. Here add usb_disabled() check in usb_serial_register to fix it.
