[PATCH AUTOSEL for 4.9 28/50] phy: increase size of MII_BUS_ID_SIZE and bus_id

From: Levin, Alexander (Sasha Levin)
Date: Tue Oct 24 2017 - 21:57:59 EST


From: Volodymyr Bendiuga <volodymyr.bendiuga@xxxxxxxxx>

[ Upstream commit 4567d686f5c6d955e57a3afa1741944c1e7f4033 ]

Some bus names are pretty long and do not fit into
17 chars. Increase therefore MII_BUS_ID_SIZE and
phy_fixup.bus_id to larger number. Now mii_bus.id
can host larger name.
