I have a trivial comment.
It would be better to add some macro for checking MMC_PM_KEEP_POWER.
And I just wonder how the problem is silent. O

Hi, Alban.
I think that it needs be set to "non-removable" for emmc.
If emmc is set to removable, it should be removed when entered suspend.

to make sure it is eMMC but missed during mmc_rescan_try_freq.
The below patch adds the check for card type before calling hardware reset
for init as double safety measure.
