sh_eth: factor out common code from MDIO bitbang methods
sh_mm[cd]_ctrl() and sh_set_mdio() all look mostly the same -- factor out their common code and put it into sh_mdio_ctrl(). Signed-off-by: Sergei Shtylyov <sergei.shtylyov@cogentembedded.com> Acked-by: Simon Horman <horms+renesas@verge.net.au> Signed-off-by: David S. Miller <davem@davemloft.net>
