Re: [PATCH] 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.

Applied for next, thanks!

Kind regards
