Hi, I'd like to cleanup and mainline Linux Sunxi SoC AW USB host driver [1]. What are the most ugly parts which should be replaced? Loading module does not complain about anything? [267044.912155] awusb: loading out-of-tree module taints kernel. [267044.912257] awusb: module verification failed: signature and/or required key missing - tainting kernel [267044.913399] usbcore: registered new interface driver allwinner [267044.913401] awusb: v0.5:AW USB driver BTW should it go to the host/Kconfig or misc/Kconfig or elsewhere? Thanks for info. Kind regards, Petr [1] https://github.com/linux-sunxi/sunxi-livesuite/blob/master/awusb/awusb.c
