The following link describes a (relatively) simple way to test a patch: https://kernel-team.pages.debian.net/kernel-handbook/ch-common-tasks.html#id-1.6.6.4 I've adapted the patch to the 6.1 kernel so it _should_ work, but haven't tried it myself. With your freshly build kernel you can verify if it indeed fixes the problem for 6.1 kernels. HTH, Diederik

Subject: [PATCH] phy: rockchip: naneng-combphy: compatible reset with old DT
The device tree of RK3568 did not specify reset-names before.
So add fallback to old behaviour to be compatible with old DT.
