(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.
