[PATCH] drm/bridge-connector: Fix bridge in drm_connector_hdmi_audio_init()

[Chaoyi Chen]

From: Chaoyi Chen <chaoyi.c...@rock-chips.com>

The bridge used in drm_connector_hdmi_audio_init() does not correctly
point to the required audio bridge, which lead to incorrect audio
configuration input.

Fixes: 231adeda9f67 ("drm/bridge-connector: hook DisplayPort audio support")
