The earlier headphone pop-noise fix leaves out the headset-mode setup. [Fix] Chain the headset-microphone and headset-mode fixup after the headphone pop-noise fixup in the Realtek HDA codec driver. Upstream commit 608c0c8947f03069b651ace54538a115f5b23123 is in the sound tree and linux-next, It fixes the regression introduced by headphone pop-noise fix 97272a5704bf, which is in v7.2. [Test Plan] On an affected Dell QCx1255 models, plug in a headset with a microphone and select the headset microphone as the recording input. List the ALSA capture devices: arecord -l Record five seconds while speaking, using the card and device numbers shown above for the Realtek codec: arecord -D plughw:CARD,DEVICE -f S16_LE -r 48000 -c 1 -d 5 /tmp/headset-mic.wav aplay /tmp/headset-mic.wav Replace CARD and DEVICE with those numbers. Without the patch, the headset microphone does not record speech. With the patch, the recording contains speech from the headset microphone. [Where problems could occur] The change affects headset pin setup on Dell systems using this Realtek HDA fixup. If the chained fixup selects the wrong input pins, the headset microphone may still be silent or the built-in microphone may stop working. If the fixup changes headphone routing, headphone pop noise could return. To manage notifications about this bug go to: https://bugs.launchpad.net/hwe-next/+bug/2169175/+subscriptions
