  Revert "driver core: Set fw_devlink=on by default" (2021-02-19 08:51:04 +0100)

Driver core / debugfs update for 5.12-rc1

Here is the "big" driver core and debugfs update for 5.12-rc1

This set of driver core patches caused a bunch of problems in linux-next
for the past few weeks, when Saravana tried to set fw_devlink=on as the
default functionality.  This caused a number of systems to stop booting,
and lots of bugs were fixed in this area for almost all of the reported
systems, but this option is not ready to be turned on just yet for the
default operation based on this testing, so I've reverted that change at
the very end so we don't have to worry about regressions in 5.12.  We
will try to turn this on for 5.13 if testing goes better over the next
few months.

Other than the fixes caused by the fw_devlink testing in here, there's
not much more:
	- debugfs fixes for invalid input into debugfs_lookup()
	- kerneldoc cleanups
	- warn message if platform drivers return an error on their
	  remove callback (a futile effort, but good to catch).

All of these have been in linux-next for a while now, and the
regressions have gone away with the revert of the fw_devlink change.
