Subject: mmc: add type field to cards
X-Git-Tag: v2.6.22-rc1~1032^2~22
X-Git-Url: http://pilppa.org/gitweb/?a=commitdiff_plain;h=9c2c0af950345e63ef86f28eca44333a1e1e709b;p=linux-2.6-omap-h63xx.git

mmc: add type field to cards

Split out the type of card into its own field as it hardly
qualifies as a state.
