Module Name: src
Committed By: pgoyette
Date: Sat Dec 16 06:39:07 UTC 2017
Modified Files:
src/sys/dev/pad: pad.c
src/sys/modules/pad: Makefile
Added Files:
src/sys/modules/pad: pad.ioconf
Log Message:
Use config(1) and IOCONF= to generate most of the auto-config data
structures. (Note that bin/52823 documents the reasons for still
requiring hand-crafted cfattach structures.)
