Claude review: drm/mediatek: hdmi: Convert DRM_ERROR() to drm_err()

[Claude Code Review Bot <claude-review@example.com>]

Patch Review

**Status: Looks good**

The conversion is correct:

- `bridge->dev` is `struct drm_device *` (confirmed from `drm_bridge.h:1104`), which is the correct first argument for `drm_err()`.
- The `__func__` prefix was correctly removed — `drm_err()` already includes device identification in its output, so the function name is unnecessary (and the original `__func__` usage was unusual for this kind of error message anyway).
- After the patch, no `DRM_ERROR` calls remain in `mtk_hdmi.c`, so the conversion is complete for this file.
- The error message text is clear and adequate.

**Minor nit:** The error message string says `"DRM_BRIDGE_ATTACH_NO_CONNECTOR must be supplied\n"` — while this is functionally fine and matches the flag name, a slightly more descriptive phrasing like `"The flag DRM_BRIDGE_ATTACH_NO_CONNECTOR must be supplied\n"` (preserving the original's wording minus `__func__`) would be marginally clearer to someone reading logs. This is very minor and not worth blocking on.

**Verdict:** Patch is correct and complete. No issues.
