[PATCH v3 0/3] ACPI/device_sysfs: Add sysfs support for _HRV hardware revision

[Betty Dall]

The ACPI _HRV object on the device is used to supply Linux with the
device's hardware revision. This is an optional object. Add sysfs support
for the _HRV object if it exists on the device.

This change allows users to easily find the hardware version of non-PCI
hardware by looking at the sysfs 'hrv' file. It is most useful for
non-PCI devices because lspci can list the hardware version for PCI
devices.

v1->v2
	Changed hrv_show error return to -EIO.
	Changed sun_show and status_show error return to -EIO.
	Cleaned up checkpatch errors and warnings.

v2->v3
	Left some of the checkpatch warnings in place.
