** Description changed: - This bug is for tracking purpose. + [Impact] + In the ubuntu 20.04, we plan to integrate sof-firmware v1.4.2, the + topology of this version contains volume and led control, we need + to add this support in the sof driver, otherwise the sof will crash + when parsing the topology of v1.4.2. After adding these patches, + the sof still coudl work with topology without volume and led control. + + [Fix] + Backported the patches from mainline kernel v5.5-c1 + + [Test Case] + Install the sof-firmware v1.4.2 + boot the kernel with these patches, sof driver initializes successfully, + and we could get a working sound card after booting up. + + Install the sof-firmware v1.3.1 + boot the kernel with these patches, sof driver initializes successfully, + and we could get a working sound card after booting up. + + [Regression Risk] + Low, the patches are backported from upstream kernel, and I tested + this patch on Lenovo and Dell dmic machines.
