I like this. There is way too much code where it sets a variable and
then checks it again a couple lines down instead of just handling it
immediately so that every line is clear without having to keep track
so many variables.
But the automated patch doesn't really go far enough in cleaning up this
function.

This for loop is nonsense. Probably it was left over cruft. It should
be:
for (i = 0; i < num_ids; i++) {
> current_id = ((u32 *)cpt_buf)[i];

return result;
Why break when it's just going to return? Eliminate the need to track
this error.

return VMCI_SUCCESS;
Then we can remove the initialization for "result" as well to eliminate
another forced look up to the start of the function and down.
