From 6bc37729df640748ed1718e3f150d63cbff1dc7e Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Wed, 10 Apr 2019 05:13:29 -0400 Subject: media: meson: ao-cec: use new cec_notifier_parse_hdmi_phandle helper The meson CEC driver increased the HDMI device refcount when it shouldn't. Use the new helper function to ensure that that doesn't happen and to simplify the driver code.
