From d81d9d6b9f7d0af7d4341951d48d296681878f7a Mon Sep 17 00:00:00 2001 From: Kay Sievers Date: Sun, 13 Aug 2006 06:17:09 +0200 Subject: 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.
