Claude review: MAINTAINERS: adjust file entry in GPU BUDDY ALLOCATOR

Patch Review

**Commit message:** Clear and well-written. It correctly identifies the two commits that introduced the problem and explains both changes (path fix + alphabetical ordering).

**Code changes:**

The fix replaces the non-existent path with the correct one:
```
-F:	drivers/gpu/drm_buddy.c
+F:	drivers/gpu/drm/drm_buddy.c
```

I verified against the kernel tree:
- `drivers/gpu/drm_buddy.c` — **does not exist** (confirmed)
- `drivers/gpu/drm/drm_buddy.c` — **exists** (confirmed)
- `drivers/gpu/buddy.c` — **exists** (confirmed)
- `drivers/gpu/tests/gpu_buddy_test.c` — **exists** (confirmed)
- `include/drm/drm_buddy.h` — **exists** (confirmed)
- `include/linux/gpu_buddy.h` — **exists** (confirmed)

All file entries after the patch reference files that exist in the tree.

The alphabetical reordering is also correct:
```
 F:	drivers/gpu/buddy.c
+F:	drivers/gpu/drm/drm_buddy.c
 F:	drivers/gpu/tests/gpu_buddy_test.c
+F:	include/drm/drm_buddy.h
 F:	include/linux/gpu_buddy.h
```

This follows `b` < `d` < `t` for `drivers/gpu/` entries and `d` < `l` for `include/` entries.

**No issues found.** Reviewed-by worthy.
