regmap: kunit: Add some test cases and a few small
Merge series from Richard Fitzgerald <rf@opensource.cirrus.com>:
This series adds some more test cases, mainly for testing:
commit eaa03486d932 ("regmap: maple: Fix uninitialized symbol 'ret' warnings")
commit 00bb549d7d63 ("regmap: maple: Fix cache corruption in regcache_maple_drop()")
And the pending patch ("regmap: Add regmap_read_bypassed()")
There are also a few small improvements to the KUnit implementation.
