Should not ABI/... patches go to someone? Who? Did you use
get_maintainer.pl? I think you should at least include the main kernel
list? Maybe someone filters messages looking for ABI changes?
CCing Greg is a good idea here. The hunk doesn't really to go via his
tree AFAIK but an ack from him might be good.
Ok, will do.

Nit: It doesn't need to be a PCA954x mux, it could be any mux.
And maybe say that it only exists for mux devices?
Maybe I'm misunderstanding you, but does the filename of
sysfs-bus-i2c-devices-pca954x not already convey that information?
Thanks,
