Yes.

I don't think you need mmc_card_set_sleep_notify() and the
corresponding new MMC_STATE_SLEEP_NOTIFY , mmc_device_prg_state(),
etc.

Overall, I think this patch could be simplified yet another step.

Why?

One final question, I noticed that you have removed the check for
MMC_CAP2_FULL_PWR_CYCLE in the _mmc_suspend() function, why?

Kind regards
