[PATCH v2 0/2] regmap: Fix cache lifecycle locking and teardown

[Michael Reeves via B4 Relay]

Fix an "Invalid wait context" lockdep warning during Apple GPIO probe and
correct debugfs ordering during cache teardown.

Tested on Apple M3 MacBook Air (T8122):

- All 4 GPIO controllers probe successfully with lockdep enabled.
- The "Invalid wait context" warning no longer occurs.
- The regmap KUnit suite passes and lockdep remains enabled.

---
Changes in v2:
- Link to v1: https://lore.kernel.org/r/20260925-regcache-lifecycle-submit-v1-1-83b75ca79d96@xxxxxxxxx
- Make Maple cache teardown IRQ-safe.
- Fix debugfs ordering during cache teardown and reinitialization.
- Rebase onto the latest upstream tree.
