Patch Review

**Change:**
```diff
-M:	Adrien Grassein <adrien.grassein@gmail.com>
+M:	Francesco Dolcini <francesco@dolcini.it>
```

**Review:**

- **Correctness:** The MAINTAINERS entry is updated cleanly — the section name, status, file patterns, and format are all preserved. The line number context matches the current drm-next tree (line 15022 in the tree, consistent with the patch context at line 15019).

- **Procedural note:** The commit author is `Francesco Dolcini <francesco.dolcini@toradex.com>` (Toradex email), but the new M: line uses `<francesco@dolcini.it>` (personal email). This is intentional and fine — maintainer entries commonly use personal emails for longevity beyond any single employer. The Signed-off-by uses the Toradex address, which is correct for the entity making the contribution.

- **Acked-by consideration:** The outgoing maintainer Adrien Grassein is Cc'd, which is good practice. Ideally an `Acked-by: Adrien Grassein <adrien.grassein@gmail.com>` would be present to confirm the handoff explicitly, but the commit message states Adrien is not interested in maintaining it anymore, implying this was discussed. This is a social/process matter rather than a code issue.

- **No issues found.** The patch is correct and ready to merge.
