Since commit "193ab2a usb: gadget: allow multiple gadgets to be built" the udc controllers can be compiled as a module. The ci13xxx_msm driver is missing the MODULE_LICENSE statement, so loading fails with: ci13xxx_msm: module license 'unspecified' taints kernel. ci13xxx_msm: Unknown symbol dev_set_name (err 0) ci13xxx_msm: Unknown symbol platform_get_irq (err 0) ci13xxx_msm: Unknown symbol device_unregister (err 0) ci13xxx_msm: Unknown symbol usb_add_gadget_udc (err 0) ci13xxx_msm: Unknown symbol put_device (err 0) ci13xxx_msm: Unknown symbol platform_driver_register (err 0) ci13xxx_msm: Unknown symbol platform_get_resource (err 0) ci13xxx_msm: Unknown symbol device_register (err 0) ci13xxx_msm: Unknown symbol usb_del_gadget_udc (err 0) This patch adds the missing MODULE_LICENSE statement with GPL v2 according to the header of the driver.
