I think they can be updated independently.

Currently in each version, they do not match their versions:
Scarthgap:
./meta/recipes-kernel/lttng/lttng-ust_2.13.10.bb
./meta/recipes-kernel/lttng/lttng-modules_2.13.12.bb
./meta/recipes-kernel/lttng/lttng-tools_2.13.13.bb

Wrynose:

./meta/recipes-kernel/lttng/lttng-ust_2.14.0.bb
./meta/recipes-kernel/lttng/lttng-modules_2.14.4.bb
./meta/recipes-kernel/lttng/lttng-tools_2.14.1.bb

master:
./meta/recipes-kernel/lttng/lttng-ust_2.15.1.bb
./meta/recipes-kernel/lttng/lttng-tools_2.15.1.bb
./meta/recipes-kernel/lttng/lttng-modules_2.15.2.bb

I have added already a patch for lttng-tools in the previous batch.
I'll check lttng-modules

Cheers,
Daniel
