From 7957b07b559175500b2a03e8a39738c1b4a832fe Mon Sep 17 00:00:00 2001 From: Matt Redfearn Date: Thu, 19 Oct 2017 12:55:34 +0100 Subject: clocksource/drivers/mips-gic-timer: Remove pointless irq_save,restore The function gic_next_event is always called with interrupts disabled, so the local_irq_save / local_irq_restore are pointless - remove them.
