There has recently been a change to the kernel.bbclass in oe-core that fixes an issue with regards to the module install stage. The mail claims that this applies to 6.5 kernels, but I've only ever encountered it with 6.6 kernels. We should verify that before merging this PR.

I ran a bitbake linux-lxatac -c do_cleanall followed by a bitbake linux-lxatac and the build went just fine.

Building a 6.6-rc2 kernel in my workspace does however fail as expected:

ERROR: linux-lxatac-6.5-r0 do_install: ExecutionError('…s/meta-lxatac/build/tmp/work/lxatac-oe-linux-gnueabi/linux-lxatac/6.5-r0/temp/run.do_install.764183', 1, None, None)

I think the original reported in the mail was just a bit un-precise and merging this PR should be fine. Getting 6.6 to work is however a problem for future us.
