I might be dropping the "local error handling" patches (as Conny and
Christian properly asked for the reason). Although they are not wrong,
they are only useful if performing checks on error pointers (*errp) or
when relying on the error to indicate the "return value" of a function.
And as I might be handling plugging of memory devices in subfunctions
(to keep the handler short as requested by Igor), this might not be
needed on this level.
