irq: remove unused flags argument from __handle_irq_event_percpu()
The __IRQF_TIMER bit from the flags argument was used in add_interrupt_randomness() to distinguish the timer interrupt from other interrupts. This is no longer the case. Remove the flags argument from __handle_irq_event_percpu(). Signed-off-by: Sebastian Andrzej Siewior <bigeasy@linutronix.de> Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
