SOF driver selects a non-existent topology file instead of falling through to function topologies. [ Fix ] Cherry-pick upstream commits: - 3bcdbc221d676 ("ASoC: Intel: soc-acpi-intel-ptl-match: Remove cs42l43 match from sdw link3") - da230e2323527 ("ASoC: SOF: ipc4-topology: set playback channel mask") [ Test Plan ] 1. Boot patched kernel on PTL system with CS42L43+CS35L57 2. Verify audio playback and recording work 3. Verify no UBSAN warnings in dmesg [ Where problems could occur ] No audio on PTL systems with cs42l43-only on SoundWire link 3 (no amplifiers) that previously matched the removed static table entry.
