[PATCH v3 2/3 net-next] net: phy: disregard "Clause 22 registers present" bit in get_phy_c45_devs_in_pkg

[Heiner Kallweit]

Bit 0 in register 1.5 doesn't represent a device but is a flag that
Clause 22 registers are present. Therefore disregard this bit when
populating the device list. If code needs this information it
should read register 1.5 directly instead of accessing the device
list.
