From 70b7aa7a87b4593f50f634dc721e18bd1f9e5448 Mon Sep 17 00:00:00 2001 From: John Keeping Date: Thu, 23 Mar 2017 10:59:29 +0000 Subject: pinctrl: rockchip: convert to raw spinlock This lock is used from rockchip_irq_set_type() which is part of the irq_chip implementation and thus must use raw_spinlock_t as documented in Documentation/gpio/driver.txt.
