Subject: [PATCH v3 0/2] drm: Allow encoder modeset when connectors are
 changed

Call encoder mode_set() when connectors are changed. This avoids issues
for cases where the connectors are changed but CRTC mode is not.

---
Changes in v3:
- BUILD_BUG_ON() for encoders and connectors array size check (Dmitry)
- Added more descriptive, file-specific names for helper functions
  (Dmitry)
- Added comment to test documenting what the test does (Dmitry)
- Return drm_connector_helper_get_modes_fixed() directly for encoder
  get_modes() instead of returning 1 (Dmitry)
- Move local variable declarations to top of function (Dmitry)
- Link to v2: https://lore.kernel.org/r/20241209-abhinavk-modeset-fix-v2-0-4d008f6ea8d0@quicinc.com

Changes in v2:

- Added kunit test
