[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. Tested on a G4/466 with a PCI card: 0001:10:13.0 Serial controller: Timedia Technology Co Ltd PCI2S550 (Dual 16550 UART) (rev 01) (prog-if 02 [16550]) Subsystem: Timedia Technology Co Ltd Unknown device 5079 Control: I/O+ Mem- BusMaster- SpecCycle- MemWINV- VGASnoop- ParErr- Stepping+ SERR- FastB2B- Status: Cap- 66MHz- UDF- FastB2B+ ParErr- DEVSEL=medium >TAbort- <TAbort- <MAbort- >SERR- <PERR- Interrupt: pin A routed to IRQ 53 Region 0: I/O ports at f2000800 [size=32] Region 2: I/O ports at f2000870 [size=8] Region 3: I/O ports at f2000860 [size=8] Signed-off-by: Olaf Hering <olaf@aepfle.de> Cc: Benjamin Herrenschmidt <benh@kernel.crashing.org> Cc: Paul Mackerras <paulus@samba.org> Cc: Adam Belay <ambx1@neo.rr.com> Cc: Dmitry Torokhov <dtor@mail.ru> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
