From e3487e07b88e4a6c3782e87416b62d5d8978936a Mon Sep 17 00:00:00 2001 From: Tomi Valkeinen Date: Wed, 27 May 2015 10:39:52 +0300 Subject: [PATCH] drm/tilcdc: use pm_runtime_irq_safe() tilcdc calls runtime PM get/put functions everywhere. Some of those places will be called in irq context, crashing the driver. As a quick fix, use pm_runtime_irq_safe() for tilcdc.
