For some reason, "videobuf2_memops" is not getting removed. So removing manually.
Reference output:
$ lsmod | grep video
videobuf2_memops 16384 0
videobuf2_common 81920 1 videobuf2_memops
mc 81920 1 videobuf2_common
video 73728 1 nouveau

Removed installing linux-headers-generic. Since, it is in development, new versions are released regularly and it leads to installing a kernel version greater than the local kernel version. For example, default kernel for U24 is 6.8.0-31 and this command installs 6.8.0-40.

I suggest to verify on one of our NUC setups. They have specific default media setup with loaded sensor driver which conflicts on patched modules loading. |
So you recommend updating the kernel on one of our U22 NUCs? |

@Arun-Prasad-V looks like a rebase is required to fix CI issues |

I tested the developed branch on Ubuntu 22.04, and it works fine; thanks for the fix! |
