Error message from device_rename in drivers/base/core.c

[Larry Finger]

I am getting the following error message from drivers/base/core.c:

net eth1: device_rename: sysfs_create_symlink failed (-17)

Upon investigation, the call generating the error is renaming 'eth1' to 'eth1'. The following patch 
suppresses the error.
