Can we move these comments to kernel-doc style please
Sure, I'll move all struct and enums.

why WARN_ON and not return error!
these helpers were intended to be as simple as possible.
I can go through with all of the WARN_ONs and replace them with if()
pr_warn() and either just return or return with 0.
Would that be acceptable?
This should never happens in working system unless there is buggy code.
I think It can be just removed
