Thanks!

Minute issue, you seem to have some spell-check going on or something,
because the subject of patch 1/4 has been "corrected" from
"...add ti,ds90c185" to "...add ti, ds90c185"

You might want to evaluate if that auto-correction "feature" should be
disabled/tweaked/whatever...

Cheers,
Peter
