I though so, but as usual I am not sure what to do when we are fixing something
in the middle of a cycle... Raw support went in v6.3-rc1 and we are now in
v6.3-rc7, so if you want to pick this up now (as it seems the case) it will fix
the above yes, but it is anyway still on an unreleased kernel...so nothing really
to have to apply on any early stable kernels...buh..I dont know what is the rule,
but the Fix tag seems harmless ... so why not :D

Thanks,
Cristian
