+Subject: [PATCH] drm/vc4: hdmi: Use local vc4_hdmi directly
+
+The function vc4_hdmi_connector_detect access its vc4_hdmi struct by
+dereferencing the pointer in the structure vc4_dev. This will cause some
+issues when we will have multiple HDMI controllers, so let's just use the
+local variable for now instead of dereferencing that pointer all the time,
+and we'll fix the local variable later.
