usb_gadget_wakeup - tries to wake up the host connected to this gadget
int usb_gadget_wakeup (struct usb_gadget * gadget);
gadget controller used to wake up the host
Returns zero on success, else negative error code if the hardware
doesn’t support such attempts, or its support has not been enabled by
the usb host. Drivers must return device descriptors that report their
ability to support this, or hosts won’t enable it.
This may also try to use SRP to wake the host and start enumeration,
even if OTG isn’t otherwise in use. OTG devices may also start remote
wakeup even when hosts don’t explicitly enable it.
