Compilation in kernel 6.1 is broken

[mad-jsanjuan]

There is something in 6.1 that has changed the way some of the defined guards for VXWORK work. We get this error:

  CC [M]  /home/docker/mdis_test_system/actions-runner/_work/13MD05-90/13MD05-90/mdis_test_system/MDIS_Compilation_Test/OBJ/dbg/men_chameleon/chameleonv2.o

We need to fix this and also find why this only affects 6.1 and not older versions.

The issue is that they have added -Werror in the main Makefile in the kernel: https://github.com/torvalds/linux/commit/3fe617ccafd6f5bb33c2391d6f4eeb41c1fd0151

Almost fixed. Just missing this one bit: https://github.com/MEN-Mikro-Elektronik/13MD05-90/issues/283

Closing the issue. Further discussions should be done in #283 or in a new ticket.
