Merge tag 'staging-5.4-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging
Pull staging/IIO driver fixes from Greg KH:
"Here are some staging and IIO driver fixes for 5.4-rc3.
The "biggest" thing here is a removal of the fbtft device and flexfb
code as they have been abandoned by their authors and are no longer
needed for that hardware.
Other than that, the usual amount of staging driver and iio driver
fixes for reported issues, and some speakup sysfs file documentation,
which has been long awaited for.
All have been in linux-next with no reported issues"
