From f4a3c6a44b351fc2cd79b1494606c84c46865024 Mon Sep 17 00:00:00 2001 From: Robin Murphy Date: Fri, 3 May 2019 16:31:43 +0100 Subject: [PATCH] drm/panfrost: Disable PM on probe failure Make sure to disable runtime PM again if probe fails after we've enabled it. Otherwise, any subsequent attempt to re-probe starts triggering "Unbalanced pm_runtime_enable!" assertions from the driver core.
