I think you mean to use MODULE_PARM in non-MODULE code, too, e.g.
in driver foo.o:
This should recognize boot options " foo.quux=2,3,4"
(resulting in bar=1, quux[0]=2, quux[1]=3, quux[2]=4 in foo.o). OK?
(If there's no "bar" option for "foo" registered, but an old-style
foo_setup is, we fall back to call that one with
foo_setup("bar,1", { 0, ...}) ).
Good idea, no problem at all. (Well, except for the MODULE_PARM macro
itself, I might need an additional parameter.)
Cheers, Roderich
