[PATCH 0/4] drm/msm/adreno: fix runtime PM imbalance at unbind

From: Johan Hovold
Date: Tue Feb 21 2023 - 05:16:51 EST


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 removes a bogus pm_runtime_set_active() call and
drops the redundant pm_runtime_disable() from adreno_gpu_cleanup().
Included is also a related indentation cleanup.
