This patch fixes the borked v5 code.
Do you mean that an out-of-tree module could enter the buggy
code path?
I mean that anything that can call ccp_run_cmd() (in ccp.ko) can run
into a problem, yes. Is this likely? We don't know, as we don't know
if anyone actually uses this layer. But it _is_ possible to find the
problem.
