The most important fix here is for missing dropping of the RCU read lock when syncing maple tree register caches, the physical devices I have that use the code don't do any syncing so I'd only ever tested this with virtual devices and missed the fact that we need to drop the lock in order to write to buses that need to sleep. Otherwise there's a fix for an edge case when splitting up large batch writes which has been lurking for a long time, a check to make sure nobody writes new drivers with a bug that was found in several SoundWire drivers and a tweak to the way the new kunit tests are enabled to ensure they don't cause regmap to be enabled when it wouldn't otherwise be. -----BEGIN PGP SIGNATURE----- iQEzBAABCgAdFiEEreZoqmdXGLWf4p/qJNaLcl1Uh9AFAmR15dQACgkQJNaLcl1U h9BGKgf+NFD98ZNPsvOoFqAdG33yTDWISTf8FtIakM074vhz0xrBTFolqf/wmBGF 8VEabgfpmLSyuGEizjK/YLDK4f143XBgivyXUH04vGeAQUx4MfBaf0DSxBlQLh4K K3LebH5QNQqdv9Qx7xMy7Y06r3KiQUxUvM8AINukspY0pmY8LtxyGLvv8T3kSpjz WU28umwPrNsr36TcSuowncvZmMJ7Y1kSEnNjer1cdVlJVn4cFzkl/Sashmy8Rg3g 5Qmbg6Kuc6mLetoshtsculYntoLUJeCt6oX01Iq3cxVqkNi+mpOgwMOgjFFlwtrc fela1GXUFEKe31FKyQPE0DRKv697eg== =iAaD -----END PGP SIGNATURE----- Merge tag 'regmap-fix-v6.4-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap Pull regmap fixes from Mark Brown: "The most important fix here is for missing dropping of the RCU read lock when syncing maple tree register caches, the physical devices I have that use the code don't do any syncing so I'd only ever tested this with virtual devices and missed the fact that we need to drop the lock in order to write to buses that need to sleep.

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.
