Subject: [PATCH v2 11/12] ASoC: Intel: bytcr_wm5102: Add jack detect support
Date:   Sun, 17 Jan 2021 17:05:54 +0100
Message-Id: <20210117160555.78376-12-hdegoede@redhat.com>

Add jack detect support by creating a jack and calling
snd_soc_component_set_jack to register the created jack
with the codec.
