[PATCH] drm/panel: fix kernel-doc warning for devm_drm_panel_add()

[Dongyang Jin]

Use the correct kernel-doc notation for struct members to eliminate
kernel-doc warnings:

Warning: drivers/gpu/drm/drm_panel.c:119 function parameter 'dev'
 not described in 'devm_drm_panel_add'
Warning: drivers/gpu/drm/drm_panel.c:119 function parameter 'dev'
 not described in 'devm_drm_panel_add'

Patch Review

**Status: Clean**

The patch adds a single line to the kernel-doc comment:

```c
 /**
  * devm_drm_panel_add - add a panel to the global registry using devres
+ * @dev: device to which the panel is attached
  * @panel: panel to add
```

This correctly documents the `struct device *dev` parameter of `devm_drm_panel_add()` at line 119, matching the actual function signature:

```c
int devm_drm_panel_add(struct device *dev, struct drm_panel *panel)
```

- The `@dev` entry is placed before `@panel`, matching the function's parameter order — correct kernel-doc convention.
- The description "device to which the panel is attached" is accurate — `dev` is passed to `devm_add_action_or_reset()` to tie the devres lifecycle to that device.
- The `Reported-by` / `Closes` tags properly reference the kernel test robot report.

No issues found. This is a minimal, correct fix for the reported warning.

This is a single, trivial documentation-only patch that adds a missing `@dev` kernel-doc parameter description for `devm_drm_panel_add()`. The fix is correct and straightforward.

The function at line 119 clearly takes `struct device *dev` as its first parameter, but the kernel-doc comment block only documented `@panel`. This omission causes the kernel-doc warning reported by the kernel test robot. The patch adds the missing `@dev` line in the correct position (before `@panel`, matching parameter order).

**Verdict: Looks good.** No concerns.
