Hm I wanted to test but was blocked by this:

Content-Type: text/plain; charset=WINDOWS-1252
Content-Transfer-Encoding: quoted-printable

Making the raw patch look like this:

=09const u32 *ranges;
-=09int rlen;
-=09int pna =3D of_n_addr_cells(dev);
-=09int np =3D pna + 5;
 =09int memno =3D 0, isa_hole =3D -1;

I bet the other ARM guys can help you get the format right
somehow... can't you just use git send-email?

Yours,
