In order to avoid disturbing anything drop the initial fixes and fall back to a point fix in the SMBus code where the issue was originally noticed, a more substantial refactoring of the API which ensures that all buses make the same assumptions will follow. - The generic regcache code had been forcing on async I/O which did not work with the new maple tree sync code when used with SPI. Since that was mainly for the rbtree cache and the assumptions about hardware that drove the choice are probably not true any more fix this by pushing the enablement of async down into the rbtree code. This probably also makes cache syncs for systems faster though it's not the point. - The test code was triggering use of the rbtree and maple tree caches with dynamic allocation of nodes since all the testing is with RAM backed caches with no I/O performance issues. Just disable the locking in the tests to avoid triggering warnings when allocation debugging is turned on, it's not really what's being tested" * tag 'regmap-fix-v6.5-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap: regmap: Disable locking for RBTREE and MAPLE unit tests regcache: Push async I/O request down into the rbtree cache regmap: Account for register length in SMBus I/O limits regmap: Drop initial version of maximum transfer length fixes --- 39b1428639ed2224832234f48bfce991786aa4df
