why don't you setup the class on module_init ? Then this would be a
terrible error condition here :-)

This is for the case where the PHY driver gets loaded before the PHY
framework. I could have returned EPROBE_DEFER here instead I thought
will have it this way.

looks a bit weird IMO. Is it really possible for PHY to load before ?

yeah. it actually happened when I tried with beagle and had all the
modules as built-in. Because twl4030 has subsys_initcall(), it loads
before PHY framework.

that's a bug in twl4030.

right. Will fix it.

Thanks
Kishon
