4.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Antoine Tenart <antoine.tenart@free-electrons•com>
commit c9bb86338a6bb91e4d32db04feb6b8d423e04d06 upstream.
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")
