From 873ef76bdc56561df75ef5c3f3842c3a64da795d Mon Sep 17 00:00:00 2001 From: Olaf Hering Date: Tue, 3 Oct 2006 01:13:56 -0700 Subject: [PATCH] restore parport_pc probing on powermac The last change for partport_pc did fix the common case for all PowerMacs, but it broke the case for PCI multiport IO cards. In fact, the config option CONFIG_PARPORT_PC_SUPERIO=y lead to a hard crash when cups probed the parport driver. It enables the winbond and smsc probing. Remove the PARPORT_BASE check again, parport_pc_find_nonpci_ports() will take care of it. All powerpc configs should have CONFIG_PARPORT_PC_SUPERIO=n, the code did not find anything on the chrp boards we tested it on.
