However, this change introduces two problems when mvmdio and mv643xx_eth are built as modules: - mvmdio is not loaded automatically by udev - mv643xx_eth oopses when it can't find its PHY, i.e. when mvmdio is not yet loaded The first problem can be fixed easily by adding a module alias for the respective platform device. The proposed fix for the second problem uses EPROBE_DEFER as suggested by Thomas Petazzoni when the driver can't find its PHY. These patches apply on top of Florian Fainelli's patchset. They have been tested on Marvel Kirkwood non-DT. - Simon [1] https://lkml.org/lkml/2013/3/22/247 Simon Baatz (2): net: mvmdio: define module alias for platform device mv643xx_eth: defer probing if Marvell Orion MDIO driver not loaded drivers/net/ethernet/marvell/mv643xx_eth.c | 12 +++++++++--- drivers/net/ethernet/marvell/mvmdio.c | 1 + 2 files changed, 10 insertions(+), 3 deletions(-) -- 1.7.9.5
