This bug has been forgotten for a while, sorry for that.
Since the verbs are reverse-engineered and there is a significant risk of breakage, we shouldn't apply it as default *yet*. So, instead, the workaround is applied when user explicitly specifies the model=huawei-mbx-stereo option to snd-hda-intel module.
The patch was submitted to upstream and I'm going to merge for 5.4 kernel.
