Merge tag 'staging-4.19-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging
Pull staging/IIO driver fixes from Greg KH:
"Here are a few small staging and iio driver fixes for -rc4.
Nothing major, just a few small bugfixes for some reported issues, and
a MAINTAINERS file update for the fbtft drivers.
We also re-enable the building of the erofs filesystem as the XArray
patches that were causing it to break never got merged in the -rc1
cycle, so there's no reason it can't be turned back on for now. The
problem that was previously there is now being handled in the Xarray
tree at the moment, so it will not hit us again in the future.
All of these patches have been in linux-next with no reported issues"
