he should take it via char-misc tree.

Hi Matthias,
Thanks for the patience. You should expect them to see after v4.5-rc1,
that's when Greg said he would push the patches.

I'm a bit puzzled. Wouldn't that mean that they will get into mainline
for v4.6.
I just want to know if I can take patch 3/3 through my v4.5-next branch
(which eventually will be merged into v4.6-rc1) or if I have to wait.
Thanks,
Matthias

The delay was due to Christmas holidays, this driver is 4.5 material, so
it would endup in v4.5-rc2 instead of v4.5-rc1.

Sorry for bothering you on this again, but I just checked v4.5-rc2 and
it is not present. I don't see it in char-misc-[next,testing] neither.
Looks like as if this patch got forgotten. Can you please check.

Matthias
