In the !CONFIG_USB_NOTIFICATIONS case, the argument is to a stub inline
function. Even though the argument isn't actually used, it can't be an
undefined type - and, I'm guessing, an undefined size, meaning the compiler
doesn't know how many registers/how much stack space it would occupy before
getting to the error argument.
I have a fix for this in my tree that just makes it an unsigned int in the
disabled case:
static inline void post_usb_device_notification(const struct usb_device *udev,
unsigned int subtype, u32 error) {}
> +#include <linux/watch_queue.h>
I was trying to avoid that if I could to avoid introducing the possibility of
circular deps, but that might not be a problem in this case.

? The kernel shouldn't require that to build.
