This patch is seen in next-test branch for last 4-5 days, i don't know
exactly how powerpc workflow happens, so a question - this would be
appear in linux-next soon right ? (for last 4-5 days i had been daily
checking -next, but not appearing there).

Sorry for the query for this trivial patch, i am asking because Thomas
had mentioned [1] to get setup_irq() cleanup thr' respective
maintainers (earlier it was part of tree-wide series), check -next after
-rc6 & resubmit ignored ones to him, this patch is neither in -next,
neither ignored, so i am at a loss what to do :(

And i would prefer to let each patch go thr' respective maintainers so
that only least patches has to be sent to Thomas. Bigger problem is that
core removal patch of setup_irq() can be sent to him only after making
sure that it's tree-wide usage has been removed.

afzal
