[PATCH -next] drm: verisilicon: make vs_dc_platform_driver static

[Icenowy Zheng]

The platform_driver struct isn't export and is only used for module
init/exit functions generated by module_platform_driver() macro.

Make it static to prevent namespace pollution.

This is a single, trivial patch that adds `static` to `vs_dc_platform_driver` in the Verisilicon DC driver. The change is correct and straightforward — the symbol is only referenced within the same file via `module_platform_driver()`, so it should indeed be static.

**Verdict: Looks good.**

Patch Review

**Assessment: Correct and complete.**

The patch adds `static` to the `vs_dc_platform_driver` struct:

```c
-struct platform_driver vs_dc_platform_driver = {
+static struct platform_driver vs_dc_platform_driver = {
```

I confirmed that `vs_dc_platform_driver` is only referenced in `vs_dc.c` itself — it appears at its definition (line 193) and in the `module_platform_driver()` macro invocation (line 203). There is no `extern` declaration in any header, and no other file references it. Making it `static` is the right fix to avoid the sparse/build warning about a non-static symbol without a prototype.

The commit message is clear, references the kernel test robot report, and includes a `Closes:` tag. No issues found.

**Reviewed-by: appropriate.**
