Hi, Hui I think we have misalignment here, there are two set of patches
1. The patch to load the firmware from the different path (the patches are reverted by LP #1860642. 2. The patch to fix hanging issues when sof_probe_continue() is failed[2]. Intel (Mengdong@Intel) is not planning to backport [2]patches to sof-v5.0 and mainline-kernel-5.3. But Canonical should still be able to land[1] patches to load the firmware from the different path, isn't it? We need to align how we plan to to ship the firmware, and in which version of path.

[Regression Risk] Low, just let different platforms load differnt firmware, and these patches are in the upstream kernel.
