Patch Review

This is the most relevant patch for dri-devel. The driver is clean and uses modern APIs well.

**Unused fields in `anbernic_panel_td4310_info`:**
The struct defines `prepare_delay`, `init_delay`, `disable_delay`, and `unprepare_delay`, and they are assigned values in `anbernic_vitapro_info`, but none of these fields are actually used in the prepare/unprepare functions. Only `reset_delay` and `enable_delay` are used. The unused fields should be removed.

```c
	u16 prepare_delay;
	u16 reset_delay;
	u16 init_delay;       /* unused */
	u16 enable_delay;
	u16 disable_delay;    /* unused */
	u16 unprepare_delay;  /* unused */
```

**Trailing semicolon after if block:**

```c
	if (ctx->enable_gpio) {
		ret = gpiod_set_value_cansleep(ctx->enable_gpio, 1);
		if (ret)
			goto err_enable;
	};
```

The `};` should just be `}`.

**Inconsistent error handling in `panel_anbernic_td4310_unprepare`:**
The function ignores return values from `gpiod_set_value_cansleep` and `regulator_disable`, always returning 0. This is generally fine for unprepare paths, but is inconsistent with the prepare path's careful error handling. The `mipi_dsi_multi_context` `accum_err` is also not checked/returned.

**`drm_panel_add` before `mipi_dsi_attach` with manual cleanup:**
The probe function adds the panel then attaches DSI, with manual cleanup on failure:

```c
	drm_panel_add(&ctx->panel);

	ret = mipi_dsi_attach(dsi);
	if (ret < 0) {
		dev_err(dev, "mipi_dsi_attach failed: %d\n", ret);
		drm_panel_remove(&ctx->panel);
		return ret;
	}
```

This is correct but could use `dev_err_probe` for consistency with the rest of the probe function.

**The `remove` function should use `mipi_dsi_detach` before `drm_panel_remove` — this ordering is correct.** Good.
