The way it's written you kinda do, since it t

Add an ERR_CAST() macro to complement ERR_PTR and co. for the purposes of
casting an error entyped as one pointer type to an error of another pointer
type whilst making it explicit as to what is going on.
This provides a replacement for the ERR_PTR(PTR_ERR(p)) construct.
