Hi Lee,

Quoting Lee Jones <[email protected]>:

Please use the $SUBJECT line expected by the subsystem.

The following command can help with this:

  `git log --oneline -- <SUBSYSTEM>`


I get it.

Add null check before dereferencing pointer of_id in order to avoid
a potential NULL pointer dereference.

I already mentioned why this isn't suitable.

Please see my pre-review.


You are right. Let me fix that.
