X-Git-Url: http://git.dujemihanovic.xyz/login.html?a=commitdiff_plain;h=b3c518a88278619b1e109de114c450237d03e032;p=u-boot.git

dm: usb: gadget: Fix boot breakage on sunxi platforms

Fixes commit 013116243950 ("dm: usb: create a new UCLASS ID for USB gadget
devices")

The UCLASS_DRIVER for id UCLASS_USB_GADGET_GENERIC needs to be declared
even for platforms that do not enable DM_USB_GADGET. Otherwise the driver
for their usb peripheral controller fails to bind.
