Subject: [PATCH] irqchip/irq-mvebu-gicp: add missing spin_lock init
Date: Wed, 25 Oct 2017 09:23:26 +0200 [thread overview]
Message-ID: <20171025072326.21030-1-antoine.tenart@free-electrons.com> (raw)
A spin lock is used in the irq-mvebu-gicp driver, but it is never
initialized. This patch adds the missing spin_lock_init() call in the
driver's probe function.
Fixes: a68a63cb4dfc ("irqchip/irq-mvebu-gicp: Add new driver for Marvell GICP")
Signed-off-by: Antoine Tenart <antoine.tenart@free-electrons.com>
