Hi Hans,

Seems these have all been sent with mime type of quoted-printable.
As git am really doesn't like that I ended up pulling these down from
patchwork.

Please try and sort that email issue out for future patch sets until
we get git am that works with it in standard distro packages (assuming
it ever does)

Otherwise, a bit of fuzz from the patch that dropped the of_match_ptr
protections.

Series applied to the togreg branch of iio.git and pushed out as testing for
the autobuilders to play with it.

Thanks,

Jonathan
