Hi Ulf,

Here is a non RFC version of my patch-set to wait for card_busy before
starting sdio requests. It is the same as the RFC version of the set,
but this time it has been tested no hardware which actually needs this
and I can confirm now that this fixes wifi on that hardware.

Great! Thanks, applied for next!

Great, thanks, I guess it is too late for this to go as a fix into
4.3-rcX (no worries if it is) ?

This patch-set should also allow removing this dw_mmc specific fix:

https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/drivers/mmc/host/dw_mmc.c?id=0bdbd0e88cf6b603a2196418672715b0890fb040


As this patch-set fixes this problem in a generic manner.

Care to send a patch to remove the above hack/fix?

I do not have any hardware to test this.

I've added Doug the original author of that patch to the Cc.

Dough, can you test if with the patch set from this mail thread
(merged into mmc/next) this patch:

https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/drivers/mmc/host/dw_mmc.c?id=0bdbd0e88cf6b603a2196418672715b0890fb040


Is still necessary ? Since this patch-set fixes the same issue
in the mmc core I believe that this commit can be reverted now.

I have a chromebook which has this hack/patch (more or less) in 
chromeos. I can try and backport your patches and see how it goes.

Regards,
Arend

Thanks & Regards,

Hans
