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.
