Merge tag 'regmap-v6.10' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap
Pull regmap updates from Mark Brown: "Other than a few cleanups the changes here are all in the KUnit tests, Richard Fitzgerald sent some bug fixes during the v6.9 cycle and while adding test coverage for the issues fixed did some fairly substantial improvements, both cleaning up the framework and building out the coverage" * tag 'regmap-v6.10' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap: regmap: Reorder fields in 'struct regmap_config' to save some memory regmap: kunit: Fix an NULL vs IS_ERR() check regmap: spi: Add missing MODULE_DESCRIPTION() regmap: Drop capitalisation in MODULE_DESCRIPTION() regmap: kunit: Add test cases for regmap_read_bypassed() regmap: kunit: Add cache-drop test with multiple cache blocks regmap: kunit: Replace a kmalloc/kfree() pair with KUnit-managed alloc regmap: kunit: Use a KUnit action to call regmap_exit() regmap: kunit: Add more cache-sync tests regmap: kunit: Add more cache-drop tests regmap: kunit: Run non-sparse cache tests at non-zero register addresses regmap: kunit: Run sparse cache tests at non-zero register addresses regmap: kunit: Introduce struct for test case parameters regmap: kunit: Create a struct device for the regmap regmap: kunit: Fix warnings of implicit casts to __le16 and __be16 regmap: maple: Remove second semicolon
