  drm/bridge: lvds-codec: simplify error handling (2020-07-30 09:03:44 +0200)

Driver core changes for 5.9-rc1

Here is the "big" set of changes to the driver core, and some drivers
using the changes, for 5.9-rc1.

"Biggest" thing in here is the device link exposure in sysfs, to help
to tame the madness that is SoC device tree representations and driver
interactions with it.

Other stuff in here that is interesting is:
	- device probe log helper so that drivers can report problems in
	  a unified way easier.
	- devres functions added
	- DEVICE_ATTR_ADMIN_* macro added to make it harder to write
	  incorrect sysfs file permissions
	- documentation cleanups
	- ability for debugfs to be present in the kernel, yet not
	  exposed to userspace.  Needed for systems that want it
	  enabled, but do not trust users, so they can still use some
	  kernel functions that were otherwise disabled.
	- other minor fixes and cleanups

The patches outside of drivers/base/ all have acks from the respective
subsystem maintainers to go through this tree instead of theirs.

All of these have been in linux-next with no reported issues.
