Subject: [PATCH 1/5 v5] irqchip: ingenic: Drop redundant irq_suspend / irq_resume functions
Date: Wed,  2 Oct 2019 19:25:21 +0800
Message-ID: <1570015525-27018-2-git-send-email-zhouyanjie@zoho.com> (raw)
In-Reply-To: <1570015525-27018-1-git-send-email-zhouyanjie@zoho.com>

From: Paul Cercueil <paul@crapouillou.net>

The same behaviour can be obtained by using the IRQCHIP_MASK_ON_SUSPEND
flag on the IRQ chip.
