Hi Khem,

Thanks for the new version. I believe we have two issues linked with
this patch.


Firs, an x86 build issue:

ERROR: clang-22.1.1-r0 do_compile: Execution of 
'/srv/pokybuild/yocto-worker/qemux86-world-alt/build/build/tmp/work/x86-64-v3-poky-linux/clang/22.1.1/temp/run.do_compile.91398'

Then, a rust selftest issue:
