4.9-stable review patch. If anyone has any objections, please let me know.
------------------ From: YYS <[email protected]> commit 014580ffab654bb83256783a2b185cf6c06dffaa upstream. mtk_hdmi_setup_vendor_specific_infoframe will return before handle mtk_hdmi_hw_send_info_frame.Because hdmi_vendor_infoframe_pack returns the number of bytes packed into the binary buffer or a negative error code on failure. So correct it.
