From c9bb86338a6bb91e4d32db04feb6b8d423e04d06 Mon Sep 17 00:00:00 2001 From: Antoine Tenart Date: Wed, 25 Oct 2017 09:23:26 +0200 Subject: irqchip/irq-mvebu-gicp: Add missing spin_lock init 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.
