From 880f25d690150937e42a2e8b86c111aae8da6d08 Mon Sep 17 00:00:00 2001 From: Tian Tao Date: Mon, 15 Mar 2021 10:39:30 +0800 Subject: rtc: rtc-spear: replace spin_lock_irqsave by spin_lock in hard IRQ The code has been in a irq-disabled context since it is hard IRQ. There is no necessity to do it again.
