Well I was initially checking for delayed work being initialized,
but Johan did not like the idea of using it. Looking at
musb_init_controller(), we only initialize musb->nIrq after
pm_runtime_get_sync(), but that's no better either.. Do you have
any better ideas for something to use?
I agree in the long run we should split struct musb into smaller
structs though.
Meanwhile the new flags added in this series are bitfields, so it's
probably better to use that and overloading something that's not
strictly related.

Tony
