Thanks Alan.

I have seen that Grant sent the same patch to lkml too.
Here is the thread: http://lkml.org/lkml/2012/1/11/342

Grant: How fast do you think you are able to merge your patches?

Currently I have remove NO_IRQ from Microblaze and we use this driver which
means that driver compilation failed right now. That's why I would like to fix asap.

Thanks,
Michal
