Paulo Marques d1dd0c2391 [ACPI] fix kmalloc size bug in acpi/video.c 
acpi_video_device_find_cap() used &p instead of *p
when calculating storage size, thus allocating
only 4 or 8 bytes instead of 12...

Also, kfree(NULL) is legal, so remove some unneeded checks.

David Shaohua Li 4e10d12a3d [ACPI] Bind PCI devices with ACPI devices 
Implement the framework for binding physical devices
with ACPI devices. A physical bus like PCI bus
should create a 'acpi_bus_type', with:

.find_device:
        For device which has parent such as normal PCI devices.

.find_bridge:
        It's for special devices, such as PCI root bridge
	or IDE controller.  Such devices generally haven't a
	parent or ->bus. We use the special method
	to get an ACPI handle.

Uses new field in struct device: firmware_data

David Shaohua Li 362b06bb70 [ACPI] S3 Suspend to RAM: interrupt resume fix 
Delete PCI Interrupt Link Device .resume method --
it is the device driver's job to request interrupts,
not the Link's job to remember what the devices want.

This addresses the issue of attempting to run
the ACPI interpreter too early in resume, when
interrupts are still disabled.
