This is mostly driver specific fixes, plus an error handling fix in the core. There is a rather large diffstat for the stm32 SAI driver, this is a very large but mostly mechanical update which wraps every register access in the driver to allow a fix to the locking which avoids circular locks, the active change is much smaller and more reasonably sized. -----BEGIN PGP SIGNATURE----- iQFHBAABCgAxFiEEreZoqmdXGLWf4p/qJNaLcl1Uh9AFAl4gVcMTHGJyb29uaWVA a2VybmVsLm9yZwAKCRAk1otyXVSH0IMOB/wJszUsDT3K46IvCg0qKJhsW+vsFsuo bjk03Fsbi/v6ukcrIbRxBl50saqut8MFibSgrMTlDCkCOvQbz3C+S2N96N9SKWSX gfEYd6PzdxVkZCx8xqybB82WGXjNBzoJue7lIYe2ytCIwjasPZtBjfNW9E+6KNkC zOGoRLGSDepZRovDQM8JbALhKHw4z5a19fDOGiESuDfp3kjsTKAe8R+UXRvcsIDc mqBblGMcKOZtRw87MDlDK2iKLPJEKAS3ndr6/a8+iX02hJMb3Yu6NbMmU4/0kHfC 3xc7xoyTZW8GVnhsLchJhOBaz+TFizTqBJTCr1tjkEjPB504SZm+/Wtx =/nsR -----END PGP SIGNATURE----- Merge tag 'asoc-fix-v5.5-rc6' of https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus ASoC: Fixes for v5.5 This is mostly driver specific fixes, plus an error handling fix in the core.
