Wrote this in a non-standard manner since the normal way would exceed 80 chars. > > I also don't see why you need the cast? It is a remnant from the previous code. But I see your point, the cast is redundant, and removing it will make it possible to implement this in the normal manner without checkpatch warning about it. > > cheers > -- Thanks and Regards gautham.
