Broken usb-c to hdmi with kernel 5.18+

[mjrr15]

Well, I risked the downgrade to 5.15 and broke the booting sequence. Found a way to recover though using an SD card with Armbian. Mounted EMMC /boot after booting Armbian.

Files in EMMC /boot were named *linux515* renamed to *linux* and copied vmlinuz-linux to Image (as I could not create a symbolic link). Then saw dtbs/rockchip/rk3399-pinebook-pro.dtb was missing so copied it from the Armbian /boot/dtb/rockchip folder (after creating the folder).

All these details I found in the EMMC "/boot/extlinux/extlinux.conf" file:
