From f91f9beaa1654ce76a783fbb65fcd51a2dde29c1 Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Thu, 31 Jan 2013 15:25:49 -0700 Subject: [PATCH] staging: comedi: das08: split out bus specific code Split the bus specific ISA/PC-104 and PCI code out of this driver and create two new drivers, das08_isa and das08_pci. This allows removing all the #ifdef'ery in the das08 driver that handled if the CONFIG_COMEDI_DAS08_{ISA,PCI} options were enabled. It also makes the PCI driver cleanly Plug-and-Play since the comedi driver only has an auto_attach callback. Previously it also had an attach callback in order to handle the ISA cards. Since the PCMCIA support was already split out, we can also remove the now unused enum das08_bustype and it's use in the boardinfo. The bus specific code deals with the bustype automatically before it calls the common attach function in das08.
