Subject: media: cros-ec-cec: decrement HDMI device refcount
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=cea053bed8534cb7de0b2092a246a84e8e512f64;p=openwrt%2Fstaging%2Fblogic.git

media: cros-ec-cec: decrement HDMI device refcount

The CrosEC CEC driver never decremented the HDMI device refcount.
CEC drivers only need the HDMI device pointer as a key in the
notifier list, it never accesses the device, so there is no
need to keep a reference.
