I am not sure it's safe to carry this patch through Chris' mmc tree
due to merge conflicts with John's wireless tree.
Though, since you have changed the mmc_card_highspeed() function to be
named to mmc_card_hs(), we need to work out the dependency.
We have some options to handle this, I suggest the following.
Re-spin this patch to keep using mmc_card_highspeed() and let John
take it through his wireless tree. Thus you also need to keep the
name mmc_card_highspeed() function from the patches to the mmc core -
could you please re-spin and post new version of those patches as
well!?
Kind regards

It would be better if this patch can be handled in Chris's.
Because if the rest of changes of this patch with keeping "mmc_card_highspeed" is applied,
high-speed SDIO will be ignored in John's tree.

You are right Seungwon!
Please re-spin the patchset on the mmc core an squash the code from
this patch, into the patch "mmc: drop the speed mode of card's state".
We then need to get acks from John and Fariya.
BTW, I had a look at the rsi_reset_card() function
(drivers/net/wireless/rsi/rsi_91x_sdio.c), which handles a complete
SDIO re-initialization and I think performs "layering violations"
while doing that. I suppose it's because of lack of documentation
about the mmc/sdio core, but I really don't think an SDIO func driver
should be doing that kind of stuff by itself. There are APIs to use to
perform an SDIO reset. Two options exists:
a) Use pm_runtime_get|put in combination with a MMC_CAP_POWER_OFF_CARD
enabled host.
b) Invoke mmc_power_save|restore_host() API.

Sure! I'll send before long.
You still want to get back naming for mmc_card_highspeed?

Yes, we could expect better changes in rsi sdio soon.

It's up to you, I have no strong opinion.
