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.
