It looks like the MAINTAINERS entry isn't updated. Can you post a separate patch for that?

There doesn't seem to be a MAINTAINERS entry for this driver. Can you add
one?

Hi Hans,
I haven't add a dedicated entry in MAINTAINERS file for these drivers
because
get_maintainer script indicates to send mail to stm32's linux mailing list.
That sound enough for me but if you really want I can add entries in
MAINTAINERS file.
