[ Reason ]

The lttng-modules-dkms fails to build at install time with the current
trixie stable kernel (>= 6.12.91).

Tracked in https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1147959

[ Impact ]

Can't use lttng kernel tracing with current stable kernel.

[ Tests ]

Tested in a trixie VM with the upstream test suite.

[ Risks ]

Minimal, code change only applies to kernel version that currently fail
to build.
