Subject[PATCH] drm/v3d: Fix PM disable depth imbalance in v3d_platform_drm_probe
Date
The pm_runtime_enable will increase power disable depth.
If the probe fails, we should use pm_runtime_disable() to balance
pm_runtime_enable().

Fixes: 57692c9 ("drm/v3d: Introduce a new DRM driver for Broadcom V3D V3.x+")
