From 66619433d0fdf3e7d9f573993217b0d2cc3044fa Mon Sep 17 00:00:00 2001 From: Noam Camus Date: Tue, 8 Nov 2016 11:58:23 +0200 Subject: [PATCH] ARC: [plat-eznps] remove IPI clear from SMP operations Today we register to plat_smp_ops.clear() method which actually is acking the IPI. However this is already taking care by our irqchip driver specifically by the irq_chip.irq_eoi() method. This is perfect timing where it should be done and no special handling is needed at plat_smp_ops.clear().
