Don't populate array startup_lookup on the stack but instead make
it static. Makes the object code smaller. Also add in missing 'int' type
specifier to clean up a checkpatch warning.
Before:
text data bss dec hex filename

After:

Hi Colin
I'm guessing accidental repost? I applied this yesterday and you haven't marked
it as a resend!
