[PATCH] fbdev: atyfb: Remove unused fb_list

[Geert Uytterhoeven]

With clang and W=1:

    drivers/video/fbdev/aty/atyfb_base.c:2327:24: warning: variable 'fb_list' set but not used [-Wunused-but-set-global]
	2327 | static struct fb_info *fb_list = NULL;

Indeed, the last user of fb_list was removed in 2004, while the actual
linked list was removed in 2002.

Patch Review

**Status: Clean**

The patch removes two things:

1. The static variable declaration:
```c
-static struct fb_info *fb_list = NULL;
```

2. The assignment in `aty_init()`:
```c
-	fb_list = info;
```

Both removals are straightforward dead code elimination. The variable was only ever assigned to, never read from, which is exactly what the clang warning reports. No other references to `fb_list` exist in this file (the diff removes all of them), so there's no risk of breaking anything.

The commit message properly credits the kernel test robot report and includes the `Closes:` tag linking to the build warning.

**Reviewed-by worthy.** No concerns.

This is a single, trivial cleanup patch that removes a dead variable (`fb_list`) from the ATY framebuffer driver. The change is correct and well-motivated — the variable is set but never read, as confirmed by a clang W=1 warning. The commit message provides good historical context (last user removed in 2004, linked list removed in 2002).

**Verdict: Looks good. No issues found.**
