X-Git-Tag: MMI-PSA29.97-13-9~18934^2~65 X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=1d56c453b14854637567c838109127b8decbf328;p=GitHub%2FMotorolaMobilityLLC%2Fkernel-slsi.git mmc: dw_mmc: set the card_width bit per card. This patch sets the card_width bit of CTYPE for the corresponding card. CTYPE[31] and CTYPE[16] correspond respectively to card[15] and card[0] for 8-bit mode. And CTYPE[15] and CTYPE[0] correspond respectively to card[15] and CTYPE[0] for 1-bit or 4-bit mode.
