Heh, I'm not objecting it :)
OTOH, it's also true that ENOTSUPP is no good error code if returned to user-space. Unfortunately many codes (including what I wrote) use this code mistakenly, and they can't be changed any longer...
It's also used internally in various places without being returned to userspace, that's what's going on here - the regmap core has some specific checks for -ENOTSUPP.
