From d593411084a56124aa9d80aafa15db8463b2d8f7 Mon Sep 17 00:00:00 2001 From: Emmanuel Grumbach Date: Mon, 11 Jul 2011 10:48:51 +0300 Subject: iwlagn: simplify the bus architecture Call iwl_probe with a ready iwl_bus struct. This means that the bus layer assigns the irq, dev and iwl_bus_ops pointers to iwl_bus before giving it to iwl_probe. The device specific struct is allocated together with the common iwl_bus struct by the bus specific layer. The pointer to the aggregate struct is passed to the upper layer that holds a pointer to iwl_bus instead of an embedded iw_bus. The private data given to the PCI subsystem is now iwl_bus and not iwl_priv. Provide bus_* inliners on the way in order to simplify the syntax. Rename iwl-pci.h -> iwl-bus.h since it is bus agnostic and represent the external of the bus layer.
