[PATCH 2/5] net/cadence/at91_ether: Simplify OF dependencies

From: Guenter Roeck
Date: Tue Apr 02 2013 - 15:35:38 EST


With of_get_mac_address() and of_get_phy_mode() now defined as dummy
functions if OF_NET is not configured, it is no longer necessary to
provide OF dependent functions as front-end. Also, the two functions
depend on OF_NET, not on OF, so the conditional code was not correct
anyway.

Drop the front-end functions and call of_get_mac_address() and
of_get_phy_mode() directly instead.
