Merge tag 'driver-core-5.8-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core into master
Pull driver core fix from Greg KH:
"A single driver core fix for 5.8-rc7. It resolves a problem found in
the previous fix for this code made in 5.8-rc6. Hopefully this is all
now cleared up, as this seems to be the last of the reported issues in
this area, and was tested on the problem hardware.
This patch has been in linux-next with no reported problems"
