deprecate PHYSDEV* keys
deprecate PHYSDEV* values in the uevent environment These values are no longer needed and inconsistent with the stacking of class devices. The event environment should not carry properties of a parent device. The key PHYSDEVDRIVER is available as DRIVER, PHYDEVBUS is indentical SUBSYSTEM. Class devices should not carry any of these values. Signed-off-by: Kay Sievers <kay.sievers@suse.de> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
