+Subject: [PATCH] drm: fix HDR static metadata type field numbering
+
+According to CTA-861 specification, HDR static metadata data block allows a
+sink to indicate which HDR metadata types it supports by setting the SM_0 to
+SM_7 bits. Currently, only Static Metadata Type 1 is supported and this is
+indicated by setting the SM_0 bit to 1.
+
+However, the connector->hdr_sink_metadata.hdmi_type1.metadata_type is always
+0, because hdr_metadata_type() in drm_edid.c checks the wrong bit.
+
+This patch corrects the HDMI_STATIC_METADATA_TYPE1 bit position.
+
