I don't get this right.
Assuming that you're still talking about the same file, I find a few
instances of 'enabled', most of them in if-statements and one where it might
be set, so it looks. However, that's already in a printk statement.
I don't know about arrays and even less where these are set. Even worse, I
don't know what to put in a 'similar' line if you don't mean 'exactly the
same'.
So please state file and line numbers and the line to be inserted.

Groeten, Wim.
