The patch titled
Remove CONFIG_PARPORT_ARC, drivers/parport/parport_arc.c
has been removed from the -mm tree. Its filename is
remove-config_parport_arc-drivers-parport-parport_arcc.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: Remove CONFIG_PARPORT_ARC, drivers/parport/parport_arc.c
From: Domen Puncer <domen@xxxxxxxxxxxx>
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.
Adrian Bunk:
adapted the patch to unrelated context changes

-/* This driver is for the parallel port hardware found on Acorn's old
- * range of Archimedes machines. The A5000 and newer systems have PC-style
- * I/O hardware and should use the parport_pc driver instead.
- *
- * The Acorn printer port hardware is very simple. There is a single 8-bit
- * write-only latch for the data port and control/status bits are handled
- * with various auxilliary input and output lines. The port is not
- * bidirectional, does not support any modes other than SPP, and has only
- * a subset of the standard printer control lines connected.
