I am not 100% sure of this. This might break the boot on CA9 and TC2 at-least. There are loads of MB peripherals that need this. This will break the boot. We need to check if all the dependent modules are also at module_initcall level and if they deal with deferred probe correctly. Lot of them are legacy and may happen to be working by carefully initcall level adjustments. I will take a look at it again. I must be able to run and check on TC2 though I seem to have removed the network cable on my TC2 or office n/w is acting crazy. I will check tomorrow again or run w/o network. -- Regards, Sudeep _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
