As reported by Bjorn, we can end up with an unbalanced runtime PM disable count if unbind() is called before the DRM device is opened (e.g. if component bind fails due to the panel driver not having been loaded yet).
As runtime PM must currently stay disabled until the firmware has been loaded, fix this by making the runtime PM disable call at unbind() conditional. The rest of the series fixes further imbalances in the load_gpu() error paths and removes a bogus pm_runtime_set_active() call. Included is also a related indentation cleanup. Johan Changes in v2 - fix the runtime PM imbalance in the gpu load error paths (new) - drop the patch removing the pm_runtime_disable() from adreno_gpu_cleanup() as this function can currently still be called with runtime PM enabled if suspending the scheduler in adreno_system_suspend() at unbind fails Johan Hovold (4): drm/msm/adreno: fix runtime PM imbalance at unbind drm/msm/adreno: fix runtime PM imbalance at gpu load drm/msm/adreno: drop bogus pm_runtime_set_active() drm/msm/adreno: clean up component ops indentation drivers/gpu/drm/msm/adreno/adreno_device.c | 26 +++++++++++++--------- 1 file changed, 16 insertions(+), 10 deletions(-) -- 2.39.2
