HID: hid, make parsing event driven
Next step for complete hid bus, this patch includes: - call parser either from probe or from hid-core if there is no probe. - add ll_driver structure and centralize some stuff there (open, close...) - split and merge usb_hid_configure and hid_probe into several functions to allow hooks/fixes between them Signed-off-by: Jiri Slaby <jslaby@suse.cz> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
