I would leave out the global mutually_exclusive/ directory because that
is redundant and I see no benefit in it. Having the redundant "state"
files is probably a good idea because the global one lets you make
atomic changes of multiple cables and the other are very convenient.
What kind of object is /sys/class/extcon/max8997-muic.0/cable.0/mutually_exclusive?
Is that a file with two lines, a directory with two empty files or
a directory with symlinks to the other directories?
