I believe so. Something along these lines has already been implemented for the
device with which I am working, but was failing due to lacking your patch.

I am not able to find the patch that you submitted (bad search terms?). I also
am having a difficult time tracking down (with any certainty) the sources that
your patch would be made against.

If you could provide lines to both I would greatly appreciate it.

Thanks.
