Comment 756 for bug 1958019

I'm not too sure that this worked for the slim variant of the legion 7 gen 7, or at least jmaximusix, who uses a slim 7 too, doesn't seem to have it working neither (https://bugzilla.kernel.org/show_bug.cgi?id=216194#c49).
Also I get the very same error message regarding CSC3551 (where the serial multi-instanciate driver fails to get an irq in smi_i2c_probe).

I applied lenovo-7i-gen7-sound-6.2.0-rc3-0.0.4.patch and I have no doubt that the path is active in the currently running kernel. Unfortunately this is the only thing I know for sure, I'm sorry to be quite ignorant in most other areas regarding sound and amplifiers in Linux :-/
