+Subject: [PATCH 4/4] Mute CEC IRQ in dw-hdmi driver init
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Add muting of the CEC interrupt to initialize_hdmi_rcar_ih_mutes,
+which it previously did not have, unlike the original generic
+initialize_hdmi_ih_mutes function.
