Subject: [PATCH] irqchip/mbigen: Fix the clear register offset
Date: Tue, 25 Apr 2017 10:16:03 +0800 [thread overview]
Message-ID: <1493086563-36396-1-git-send-email-majun258@huawei.com> (raw)
From: MaJun <majun258@huawei.com>
Don't minus reserved interrupts (64) when get the clear register offset,because
the clear register space includes the space of these 64 interrupts.
