docs: draft the upstream escalations

A linux-arm-msm report for the QLINK modem crash (the error string
appears nowhere public), and a Fedora kernel-ark MR plus Bugzilla text
for enabling SND_SOC_WSA881X.

+# Draft: Fedora request to enable CONFIG_SND_SOC_WSA881X
+
+Two routes; the merge request is the one that actually changes the
+config, the bug is the paper trail. Doing both is normal: file the bug,
+open the MR, and link them to each other.
+
+## Route 1: kernel-ark merge request (preferred)
+
+Repo: <https://gitlab.com/cki-project/kernel-ark>, branch `os-build`.
+
+The current state, verified 2026-07-28:
+
+- `redhat/configs/common/generic/CONFIG_SND_SOC_WSA881X` contains
+  `# CONFIG_SND_SOC_WSA881X is not set`
+- `redhat/configs/fedora/generic/CONFIG_SND_SOC_WSA883X` contains
+  `CONFIG_SND_SOC_WSA883X=m` (the Fedora override pattern to copy)
+
+The change is one new file:
+
+```
+echo 'CONFIG_SND_SOC_WSA881X=m' > redhat/configs/fedora/generic/CONFIG_SND_SOC_WSA881X
+```

+
+redhat/configs: fedora: enable SND_SOC_WSA881X
+
+The WSA881x is the SoundWire speaker amplifier used on Qualcomm
+SDM845/SDM850 machines. The in-tree sdm850-lenovo-yoga-c630.dts
+(shipped and booted by Fedora's aarch64 kernel-core) names two WSA881x
+devices as codec DAIs of its "SLIM Playback" link, so with the driver
+absent the machine driver defers forever with
+
+  platform sound: deferred probe pending: msm-snd-sdm845:
+      SLIM Playback: codec dai not found
+
+and the sound card never registers. Every other link in the chain is
+already enabled (MFD_WCD934X, SND_SOC_WCD934X, GPIO_WCD934X,
+SOUNDWIRE_QCOM, SND_SOC_SDM845, SLIM_QCOM_NGD_CTRL, QCOM_APR,
+QCOM_PD_MAPPER are all =m), as are the newer members of the same
+driver family, SND_SOC_WSA883X and SND_SOC_WSA884X, which the ThinkPad
+X13s uses.
+
+Verified on a Lenovo Yoga C630 13Q50 (81JL) on 7.1.5-200.fc44.aarch64:
+with snd-soc-wsa881x built out of tree and installed, the
+Lenovo-YOGA-C630-13Q50 card registers, jack detection works, and the
+speaker path plays (UCM profile has been in alsa-ucm-conf since 2020).
+Without it, no sound card has ever registered on this machine on any
+Fedora release.
+
+---
+
+## Route 2: Bugzilla
+
+<https://bugzilla.redhat.com> — Product: Fedora, Component: kernel,
+Version: 44. Severity low, it is a feature enablement.
+
+Summary:
+
+    aarch64: CONFIG_SND_SOC_WSA881X not set; audio cannot work on
+    Lenovo Yoga C630 (SDM850)
+
+Description:
+
+---
+
+Fedora's aarch64 kernel has never enabled CONFIG_SND_SOC_WSA881X, the
+driver for the WSA881x SoundWire speaker amplifier used on Qualcomm
+SDM845/SDM850 hardware. The in-tree device tree
+arch/arm64/boot/dts/qcom/sdm850-lenovo-yoga-c630.dts — which Fedora
+ships in kernel-core and which boots Fedora on this laptop — requires
+two WSA881x DAIs on its "SLIM Playback" link, so the sound card is
+stuck in deferred probe on every Fedora release:
+
+  platform sound: deferred probe pending: msm-snd-sdm845:
+      SLIM Playback: codec dai not found
+
+Everything else in the audio chain is already =m: MFD_WCD934X,
+SND_SOC_WCD934X, GPIO_WCD934X, SOUNDWIRE_QCOM, SND_SOC_SDM845,
+SLIM_QCOM_NGD_CTRL, QCOM_APR, QCOM_PD_MAPPER — and notably the newer
+amplifiers in the same family, SND_SOC_WSA883X=m and
+SND_SOC_WSA884X=m (X13s-era), are enabled.
+
+Reproducer / verification, on 7.1.5-200.fc44.aarch64 on a Yoga C630
+13Q50 (81JL): building sound/soc/codecs/wsa881x.c out of tree and
+loading it makes the Lenovo-YOGA-C630-13Q50 card register immediately,
+with working jack detection and speaker playback (the UCM profile has
+shipped in alsa-ucm-conf since 2020). No other change is needed.
+
+Requested change: CONFIG_SND_SOC_WSA881X=m for Fedora, i.e. one file
+in kernel-ark:
+redhat/configs/fedora/generic/CONFIG_SND_SOC_WSA881X containing
+"CONFIG_SND_SOC_WSA881X=m", matching the existing
+fedora/generic/CONFIG_SND_SOC_WSA883X.
