From: Martyn Welch
Date: Sun Jun 05 2016 - 16:36:13 EST

The vme_register_driver() api changed in commit 5d6abf379d73 ("staging:
vme: make match() driver specific to improve non-VME64x support") but the
documentation wasn't updated. Update the documentation to match the API.

occurred a negative error code will be returned.
