For mtk_nand.c we are missing acks from (co-)authors of following commits:
1) Wei:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=07f76443ef81e2b76bb6f7858ba183cd60357ada
2) Peter:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=d4092d76a4a4e57b65910899948a83cc8646c5a5
3) Masahiro:

All are absolutely trivial.

For mtk_ecc.c are are missing acks from (co-)authors of following commits:
1) Wen:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=0119720a00b20074a51245427f05366ede2fa90a
2) Gustavo:

3) Arnd:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=8ff0513bdcdd71e84aa561cce216675d43fb41b8

The only /complex/ change is from Arnd. I'm not sure if that is
copyrightable or not.
