Linus Torvalds 7ac1161c27 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.

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
