Public bug reported:
[Impact]
Dell Renegade laptops come with Cirrus smart amplifier have inconsistent volume
issue on left/right speaker. Speaker will output from both channels even we
only expect output from single channel. It needs the updated tuning files in
linux-firmware.
[Fix]
Backport the fix from 5be0792a ("cirrus: cs35l56: Add firmware for Cirrus
CS35L56 for various Dell laptops") on linux-firmware.
[Test Case]
1. Boot up the Dell Renegade laptops.
2. Open settings->Sound->Output Device
3. Click test icon to separately test the left and right speaker
4. Verify the sound output volume by ear from left speaker and right speaker.
[Where problems could occur]
It updated tuning files for specific Dell platforms by SSIDs. No regression
expected at the current stage.
