Just a note here (the change is good)

When applying please add some kerneldoc above mmc_send_adtc_data()
and expand the ADTC acronym and add some info explaining what it
is maybe a small protocol ref or so, so readers of the code get an
intuitive feeling for what this function does and what ADTC is.
