Subject: [PATCH net-next 2/4] net: phy: bcm54140: fix phy_id_mask

Broadcom defines the bits for this PHY as follows:
  { oui[24:3], model[6:0], revision[2:0] }

Thus we have to mask the lower three bits only.

Fixes: 6937602ed3f9 ("net: phy: add Broadcom BCM54140 support")
Signed-off-by: Michael Walle <michael@...le.cc>

Please note that although this patch contains a Fixes tag its subject
contains the net-next tag, because the commit in question is only in
net-next.
