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.
