Kernel build 5.10.110 for OPi5B - dma-buf drivers fail #56

Open vrbadev opened 12 months ago

vrbadev commented 12 months ago

Hello, I wanted to build the kernel on the OPi5B (Ubuntu focal server distro image) which has Linux kernel 5.10.110, so I cloned the branch orange-pi-5.10-rk3588.

However, when building the kernel with the make command, it fails for dma-buf drivers:
