Thanks for flagging this up. The patch I submitted is written against the
Android touch devices spec, which treats ABS_MT_PRESSURE being zero as
hover, but indeed currently the handling of BTN_TOUCH when using
input_mt_report_pointer_emaultion() won't be quite right.

I will have a look at straightening this out and re-post.

cheers
