Thomas Gleixner 70433c0161 genirq: Use the correct variable for note_interrupt ... note_interrupt wants to be called with the combined result of all handlers called, not with the last one. If it's a shared interrupt then the last handler might return IRQ_NONE often enough to trigger the spurious dectector which turns off a perfectly fine working interrupt line. Bug was introduced in commit 1277a532(genirq: Simplify handle_irq_event()). Yes, I really messed up there. First the variable ret should not have been named differently to avoid similarity with retval. Second it should have been declared in the do {} loop. Rename it to res and move it into the do {} loop and vanish under a huge brown paperbag.
