next-20190904: build failure in cp210x usb serial, gpio related?

Hi!

I'm getting this compiling the -next:

CC drivers/net/wireless/intel/iwlwifi/mvm/mac80211.o
In file included from drivers/usb/serial/cp210x.c:23:

Sounds like some fixes are needed in gpio headers?

Yes this was fixed pretty much the same day the next release came out, and by now I got like 4 different patches solving the same problem, because no new next releases are coming out right now...
bad timing with no next releases during the kernel summit, sorry!
