Thanks. First I reversed the previous patch and then applied the new. 
The last chunk of hmt.c didn't apply on releng/13.0:

# cat sys/dev/hid/hmt.c.rej
_at__at_ -844,7 +855,9 _at__at_
         sc->report_id = report_id;
         sc->nconts_per_report = cont;
         sc->has_int_button = has_int_button;
+       sc->has_cont_count = cont_count_found;
         sc->cont_count_max = cont_count_max;
+       sc->has_scan_time = scan_time_found;

         return (type);
  }
#

I edited hmt.c manually to make these 6 lines read the same as the patch 
which did not build:

-------------------------

I then removed this line: "sc->cont_count_max = cont_count_max;" which 
got a successful build and hmt0/hconf0 attached. X now adds it as an 
input device:

Now when touching the touchscreen we get an immediate kernel panic. Not 
sure if this is my mistake in merging the patch or something else.
