You should never rely on the output of get_maintainers without review,
it's prone to both false positives and false negatives.  Given that
Sakamoto-san does not seem to appear in MAINTAINERS at all and you've
not managed to find Liam who's a comaintainer for all the ASoC stuff I
suspect you're doing this with --git enabled which is especially prone
to false positives since it tends to identify people who are just doing
global cleanup work and aren't particularly interested in a given file.
As far as I can tell this is how I'm getting pulled in too rather than
MAINTAINERS.
