oh sorry. I don't know why.

Here they are all: https://patchwork.kernel.org/cover/11199599/

Well, I have no plan for that except that all should end up fixed in mainline
and stable.

The issue is that multiple subsystems are involved (net/wireless, mmc and arm/omap)
and all patches should be ideally be applied in combination.

BR and thanks,
