warnings when installing a new kernel

[Colin Ian King]

I installed my own built kernel based directly on 5.8.0-16 with a minor CONFIG change that is not related to the bug reported below.

When I install the package I see the following warning. Can this be cleaned up as it doesn't look helpful when it reports it cannot apply the patch.

/etc/kernel/header_postinst.d/dkms:

Perhaps you used the wrong -p or --strip option?
