Claude review: drm/tegra: hdmi: Open-code drm_simple_encoder_init()

Patch Review

This is the version that should be considered for merge.

**Include changes (correct):**
```c
+#include <drm/drm_encoder.h>
...
-#include <drm/drm_simple_kms_helper.h>
```
The new include for `drm_encoder.h` is needed to provide `drm_encoder_init()` and `drm_encoder_cleanup()` declarations directly, and the alphabetical sort order is maintained. The stray blank line from v1 is fixed.

**New encoder funcs struct:**
```c
+static const struct drm_encoder_funcs tegra_hdmi_encoder_funcs = {
+	.destroy = drm_encoder_cleanup,
+};
```
This correctly replicates what `drm_simple_encoder_init()` provided internally. The struct is `static const`, which is the standard pattern.

**Minor style nit:** The struct is placed immediately after the closing `};` of `tegra124_tmds_config[]` on line 373 with no blank line separator. Kernel style typically has a blank line between top-level definitions. This was present in v1 too and wasn't addressed in v2's changelog.

**Call site change (correct):**
```c
-	drm_simple_encoder_init(drm, &hdmi->output.encoder,
-				DRM_MODE_ENCODER_TMDS);
+	drm_encoder_init(drm, &hdmi->output.encoder, &tegra_hdmi_encoder_funcs,
+				DRM_MODE_ENCODER_TMDS, NULL);
```
The `NULL` name parameter matches what `drm_simple_encoder_init()` passes internally. The return value of `drm_encoder_init()` is not checked, but this is consistent with the existing code — `drm_simple_encoder_init()`'s return was also being silently discarded. This is a pre-existing issue across all tegra encoder init paths (`rgb.c:308`, `dsi.c:1058`, `sor.c:3084`), and fixing it is outside the scope of this cleanup.

**Overall for v2:** Correct, minimal, no functional change. One optional nit about a missing blank line before the new struct definition. Suitable for merge as-is.
