Subject: [PATCH] Fix phy_read/write redefinition errors in ucc_geth_phy.c

From: [email-masked]
Date: Wed, 13 Dec 2006 17:08:55 -0600

From: Timur Tabi <[email-masked]>

The local versions of phy_read() and phy_write() in ucc_geth_phy.c conflict
with the prototypes in include/linux/phy.h, so this patch renames them, 
moves them to the top of the file (while eliminating the redundant prototype),
and makes them static.
