I have manually tested the commit b18247f9dab73 ("arm64: dts: rockchip: 
Do not enable hdmi_sound node on Pinebook Pro") and found that executing
`git cherry-pick b18247f9dab73` applies successfully on the linux-stable 
branches 5.10.251, 5.15.201, 6.1.164, 6.6.127, and 6.12.74. 

Could there be other reasons that cause the patch to fail to apply?

Best regards,
Jun Yan
