[PATCH 00/25] Staging: hv: Cleanup vmbus driver code

[K. Y. Srinivasan]

This patch-set addresses some of the bus/driver model cleanup that
Greg sugested over the last couple of days.  In this patch-set we
deal with the following issues:

	1) Cleanup unnecessary state in struct hv_device and 
	   struct hv_driver to be compliant with the Linux
	   Driver model.

	2) Cleanup the vmbus_match() function to conform with the 
	   Linux Driver model.

	3) Cleanup error handling in the vmbus_probe() and 
	   vmbus_child_device_register() functions. Fixed a 
	   bug in the probe failure path as part of this cleanup.

	4) The Windows host cannot handle the vmbus_driver being 
	   unloaded and subsequently loaded. Cleanup the driver with
	   this in mind.

	5) Get rid of struct hv_bus that embedded struct bus_type to 
	   conform with the LDM.

	6) Add probe/remove/shutdown functions to struct hv_driver to
	   conform to LDM.

	7) On some older Hyper-V hosts, the Linux PCI sub-sytem is not able
	   to allocate irq resources to the vmbus driver. I recently learnt
	   that the vmbus driver is an acpi enumerated device on the Hyper-V
	   platform. Added code to retrieve irq information from DSDT.
