As a consequence, whenever the firmware is loaded, a rather misleading 'Failed to parse legacy: -19' error message is written to the kernel ring buffer: [ 288.977412] steamdeck kernel: cs35l41 spi-VLV1776:01: DSP1: Firmware version: 3 [ 288.978002] steamdeck kernel: cs35l41 spi-VLV1776:01: DSP1: cs35l41-dsp1-spk-prot.wmfw: Fri 02 Apr 2021 21:03:50 W.

Indeed, I have just submitted v2 for a more generic handling of the issue: https://lore.kernel.org/all/20220825220530.1205141-1-cristian.ciocaltea@xxxxxxxxxxxxx/ Thanks for reviewing, Cristian
