Merge tag 'driver-core-6.3-rc1_2' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core
Pull driver core fixes from Greg KH:
"Here is another small set of driver core patches.
They resolve some reported problems with the previous driver core
patches that are in your tree.
They solve a problem with the bus_type cleanup as reported and fixed
by Geert, and two fw_devlink changes to make debugging problems
easier.
There is one known outstanding problem with the fw_deflink changes in
your tree that is still being worked on, and it looks like a clk core
change will be submitted soon for that, probably after 6.3-rc1.
All three of these have been in linux-next with no reported problems
(only reports that they fixed problems)"
* tag 'driver-core-6.3-rc1_2' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core:
driver core: fw_devlink: Print full path and name of fwnode
driver core: fw_devlink: Avoid spurious error message
driver core: bus: Handle early calls to bus_to_subsys()
