Stephen,

True. But without this gcc complains:

CC [M]  drivers/net/ucc_geth.o
drivers/net/ucc_geth.c: In function ‘ucc_geth_probe’:
drivers/net/ucc_geth.c:3824: warning: assignment discards qualifiers
from pointer target type

Else gcc just builds fine:

CC [M]  drivers/net/ucc_geth.o

This is an just an extra caution to fix both the build and warning
regression(s).
