Author: Wu Fengguang <fengguang.wu@intel.com>

drivers/net/phy/dp83867.c:126:1-4: WARNING: end returns can be simpified
drivers/net/phy/dp83867.c:74:5-8: WARNING: end returns can be simpified if tested value is negative or 0

 Simplify a trivial if-return sequence.  Possibly combine with a
 preceding function call.
