fixed_phy_set_link_update() contains an early check against a NULL
callback pointer, which basically prevents us from removing any
previous callback we may have set. The users of the fp->link_update
callback deal with a NULL callback just fine, so we really want to allow
"removing" a link_update callback to avoid dangling callback pointers
during e.g: module removal.

net: Allow FIXED_PHY to be modular.2014-12-16T20:02:23ZDavid S. Millerdavem@davemloft.net2014-12-16T19:30:09Zurn:sha1:6539c44d08ac2eea693b6163135169b9c8c18bb1
Otherwise we get things like:
warning: (NET_DSA_BCM_SF2 && BCMGENET && SYSTEMPORT) selects FIXED_PHY which has unmet direct dependencies (NETDEVICES && PHYLIB=y)
In order to make this work we have to rename fixed.c to fixed_phy.c
because the regulator drivers already have a module named "fixed.o".
