Re: [RFC] Fix BUG splat during nubus_driver_register()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 




Regarding zorro bus drivers - bus_register is called unconditionally 
from a core initcall for the Zorro bus code.

OK. NuBus should probably do the same then. Something like the patch below 
(instead of the one I sent earlier).

I don't understand why zorro and others call bus_register() through 
postcore_initcall() instead of arch_initcall() or subsys_initcall().

Anyway, this patch follows the same pattern.
