From 51317975565329ee50e52d0fffce50566b43cc2d Mon Sep 17 00:00:00 2001 From: Xiaofei Tan Date: Wed, 3 Feb 2021 20:39:37 +0800 Subject: rtc: pm8xxx: Replace spin_lock_irqsave with spin_lock in hard IRQ It is redundant to do irqsave and irqrestore in hardIRQ context, where it has been in a irq-disabled context.
