Subject: [PATCH] ASoC: Intel: sof_cs42l42: remap jack pins
Mime-version: 1.0
Content-type: text/plain; charset=UTF-8
Content-transfer-encoding: 8bit
Git-commit: 7459c8940a506280908f8b5e9e4227784a0b6569
Patch-mainline: v6.0-rc1
References: jsc#PED-850

The card did not map jack pins to controls, which prevents
PulseAudio/PipeWire from dealing with jack detection. It's likely that
jack detection was only tested with the CRAS server and extensions of
UCM.
