[ Upstream commit 406dcbc55a0a20fd155be889a4a0c4b812f7c18e ]
The LattePanda board has a sound card chtrt5645, when there is nothing plugged in the headphone jack, the system thinks the headphone is plugged in, while we plug a headphone in the jack, the system thinks the headphone is unplugged.
If adding quirk=0x21 in the module parameter, the headphone jack can work well. So let us fix it via platform_data.
