No, that doesn't fix it. I also don't see your printout.
OK, found the problem and posted a patch. See
<https://lkml.kernel.org/r/20181204180441.218160-1-dianders@xxxxxxxxxxxx>.
Please test and review if you are able.

OK, good to know. Probably 2/3 and 3/3 will be squashed anyway since
(as I suggested in the review) they should both be touching the MTP
device tree file.
...in any case, you should send yours out as a singleton patch and
then you don't have to guess how many patches might or might not be
sent out later. Sandeep can send out his patch and say it depends on
yours.
