Thanks for doing that.

They could.
This specific lockdep check was introduced in commit de8f5e4f2dc1
("lockdep: Introduce wait-type checks") which appeared in v5.7.
The fixes depend upon commit 67021f25d952 ("regmap: teach regmap to
use raw spinlocks if requested in the config") which appeared in v5.15.
So at least the stable 5.15 and 5.18 kernels can benefit if lockdep is
being used - that's without any extra burden of backporting the regmap
dependency commit itself any further.
