From 32797f976d62af709943aae38a9457b5a6dbcd8a Mon Sep 17 00:00:00 2001 From: Domen Puncer Date: Fri, 23 Jun 2006 02:05:14 -0700 Subject: [PATCH] Remove CONFIG_PARPORT_ARC, drivers/parport/parport_arc.c It's wasn't referenced in Makefile since at least 2.2.8, unbuildable due to trivial typos and things like DATA_LATCH and arc_write_control() which doesn't exist.
