+Subject: [PATCH] drm/vc4: hdmi: Put the device on error in
+ pre_crtc_configure
+
+In the vc4_hdmi_encoder_pre_crtc_configure() function error path we
+never actually call pm_runtime_put() even though
+pm_runtime_resume_and_get() is our very first call.
+
+Fixes: 4f6e3d66ac52 ("drm/vc4: Add runtime PM support to the HDMI encoder driver")
