From a2139d3b4fd7ef26a363a1b1eb6cd55be2c1bcd1 Mon Sep 17 00:00:00 2001 From: Valentin Schneider Date: Mon, 23 Sep 2019 15:36:14 +0100 Subject: [PATCH] csky: entry: Remove unneeded need_resched() loop Since the enabling and disabling of IRQs within preempt_schedule_irq() is contained in a need_resched() loop, we don't need the outer arch code loop.
