LTTng » LTTng-modules

Hi,

Yocto Project updates lttng-modules from 2.13.17 to 2.13.18 but on genericarm64 configuration there is a compile failure
when cross compiling for arm64 with kernel 6.12.23:

The build config is described in https://git.yoctoproject.org/poky/tree/meta/recipes-kernel/lttng/lttng-modules_2.13.18.bb
and one patch https://git.yoctoproject.org/poky/tree/meta/recipes-kernel/lttng/lttng-modules/0001-src-Kbuild-change-missing-CONFIG_TRACEPOINTS-to-warn.patch is applied on top of the release.

v2.13.17 is compiling and AFAIK working without issues.

Could you hint on how this could be fixed? Thanks
