With today's linux-next (20190731), I am still seeing a Kconfig warning and
build errors (building for i386):
and applying Greg's "depends on NETDEVICES" patch and this patch:
WARNING: unmet direct dependencies detected for MDIO_OCTEON
Depends on [n]: NETDEVICES [=y] && MDIO_DEVICE [=m] && MDIO_BUS [=m] && (64BIT [=n] || COMPILE_TEST [=y]) && HAS_IOMEM [=y] && OF_MDIO [=n]
Selected by [m]:
- OCTEON_ETHERNET [=m] && STAGING [=y] && (CAVIUM_OCTEON_SOC || COMPILE_TEST [=y]) && NETDEVICES [=y]
ERROR: "cavium_mdiobus_write" [drivers/net/phy/mdio-octeon.ko] undefined!
ERROR: "cavium_mdiobus_read" [drivers/net/phy/mdio-octeon.ko] undefined!
kernel .config file is attached.
Am I missing another patch?
thanks.
