enable kernel patch for Ubuntu 22.04
build kernel patch for Ubuntu 22.04
move to new kernel repo URL remove some “sudo” command
BTW, there should be some issue in the kernel source repo for 5.15.0-39. In my environment, I can't insert the kernel module the system.

@ev-mp @Nir-Az In order to implement Y16I for LRS-463 can we consider merging this PR to development branch?
@mengyui , since the changes are in the main script file, this PR needs to be verified for regressions for Ubuntu 16/18 and 20 at least with the latests LTS kernel for each distribution.
Hi @dmipx, the outputs of this script are not signed modules, even the origin version.
if the signed modules are required, they should be signed by another script. https://wiki.ubuntu.com/UEFI/SecureBoot/Signing
so, please turn off "Secure Boot" in BIOS.
Thanks, @ev-mp
@ev-mp - Please note the authur comment
BTW, there should be some issue in the kernel source repo for 5.15.0-39. In my environment, I can't insert the kernel module the system.
This means it will not work for Ubuntu 22 default kernel right?
@mengyui , you need to verify the script againt the older distros (16,18 and 20) as mentioned above. Please run the tests and share the results internally - this is a prerequisite for merge.
Hi @ev-mp @Nir-Az @dmipx the script works well for Ubuntu 18 (kernel 4.15) and report error "mobprobe: ERROR: could not insert 'videodev': Exec format error" on Ubuntu 20 (kernel 5.13/5.15) or Ubuntu 22 (kernel 5.15).
It is a very odd issue. I remember there is a version of the kernel source that works with this script when I create this PR. and the dkms package works well (https://github.com/mengyui/librealsense2-dkms) the building steps are not changed in this PR.
Hi @mengyui! We discussed with @ev-mp and best scenario is that we can merge all new patches but change scripts to be another ones, for example:
scripts/patch-realsense-ubuntu-lts.sh -> scripts/patch-realsense-ubuntu-lts-hwe.sh scripts/patch-utils.sh -> scripts/patch-utils-hwe.sh
so this will not require regression tests for legacy versions. Please rework and we will merge it, we need to add Y16I format for 5.13/5.15 kernels and we are blocked by this PR. Thanks!

on older kernels - Makefile changed and set "CONFIG_MODULE_SIG=n" look for example: realsense-camera-formats-xenial-Ubuntu-hwe-4.8.0-58.63_16.04.1.patch That is not good idea but thus we can understand why it was working on older kernels. The DKMS is working well indeed, the DKMS package performs module signing with x509 certificates bundled with kernel package. BTW, can you PR librealsense2-dkms to dkms4librealsense?
