Thanks very much for responding.

 From your two replies, I crafted the attached patch.
Alas, the EDID transfer comes up all zeros.
I see two possible causes of this behavior:

1. I misunderstood how you intended the file to be modified.
2. The fix for my bug is NOT in correcting the audit call, but  
instead from some other fix, perhaps from the other aspect that you  
worked on.

I know that when I surrounded the audit_syscall_exit with #if 0 I got  
correct EDID fetches, so the most likely cause is #1, that I didn't  
correctly incorporate your understanding of correct operation of the  
call to audit_syscall_exit.

Here's my patch.  Where did I screw up?
