[MMC] Add multi block-write capability
Add a capability flag for drivers to set when they can perform multi- block transfers to cards _and_ correctly report the number of bytes transferred should an error occur. The last point is very important - if a driver reports more bytes than were actually accepted by the card and an error occurs, there is the possibility for data loss. Pierre Ossman provided the patch for wbsd and sdhci. Signed-off-by: Pierre Ossman <drzeus@drzeus.cx> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
