From a4d00f179fcec7065fe5742e9cebd6500886070f Mon Sep 17 00:00:00 2001 From: Kumar Gala Date: Wed, 11 Jan 2006 11:27:33 -0800 Subject: [PATCH] phy: Added a macro to represent the string format used to match a phy device Add the PHY_ID_FMT macro to ensure that the format of the id string used by a driver to match to its specific phy is consistent between the mdio_bus and the driver.
