And instead of passing hcd->regs, wouldn't it be better to pass hcd?I really don't know.Other users of this interface might need to initialize something other than a non-standard register.Hm, maybe... if passing 'struct usb_hcd *' would indeed help here. Do you think it's worth passing 'struct platform_device *' along with it?Probably not as it can be extracted from 'hcd->self.controller'...It's up to you. Generally I think it's easier to pass an extra argument than to force the function being called to dig it out.
Note that in our use case we don't even need this argument.
