Hello,

s/arae/are/, but maybe the overall wording could be improved. Something
like:

	drivers/mmc/core/bus: Remove redundant driver match function

	If there is no driver match function, the driver core assumes
	that each candidate pair (driver, device) matches. See function
	driver_match_device().

	Drop the mmc bus's match function that always returned 1 and
	so implements the same behaviour as when there is no match
	function.

Best regards
Uwe
