Patch For Lenovo Legion 7 15IMHg05 & Yoga 7 14ITL5

[Cameron Berkenpas]

Hello,

I have a patch against 5.12.x that results in working speaker audio for 
the Lenovo Legion 7 15IMHg05 and the Lenovo Yoga 7 14ITL5.

How should I go about getting this merged? Should this be against the 
latest torvalds git? Is this the right place to present this particular 
patch? There are no issues checking my changes against checkpatch.pl.

Thanks!
