From 9d9326d3bc0ea9a8bbe40bf3e5e66c7b9858caa0 Mon Sep 17 00:00:00 2001 From: Andy Fleming Date: Wed, 9 Apr 2008 19:38:13 -0500 Subject: phy: Change mii_bus id field to a string Having the id field be an int was making more complex bus topologies excessively difficult. For now, just convert it to a string, and change all instances of "bus->id = val" to snprintf(id, MII_BUS_ID_LEN, "%x", val).
