Nitpick 1) I would like to make it clear that this is a feature, which
depends on the behavior of the mmc host. Thus, I suggest renaming the
function to something along the lines of mmc_host_*()
Nitpick 2) There is system-wide PM core feature already "reserved" the
"direct_complete" terminology. To avoid mixing them up (terminology
wise), may I suggest renaming the mmc cap to MMC_CAP_DONE_COMPLETE,
thus perhaps the function above to mmc_host_done_complete(). Or if you
find a better option. :-)

Besides the nitpicks, this looks good to me!
Kind regards
