Okay, so I have picked up the patches and applied them to my next
branch to my mmc tree. While doing that, I have also added Oleksandr's
tested-by tag for all patches, including the four mmc patches. I also
added your tested-by tags to the the four mmc patches.

Finally I made little cosmetic change to last patch in this series,
which was dropping the surrounding #ifdef CONFIG_PM while do the
assignment of .driver.pm to &rtsx_usb_ms_pm_ops, as that isn't needed.

If anybody have any objections, please tell me.

Kind regards
Uffe
