GPIO lookup tables are supposed to be zero terminated. Let's do that
and avoid accidentally walking off the end.

We have a collect-all bugzilla for all kms_flip fail, but that's pretty
useless since it's not specific to a given bug. The issue here seems to be
that we miss the vblank TS by a bit - almost always around 180msec
strangely. Not sure what's going on, but many machines in previous runs
are affected, so filed a new one:

https://bugs.freedesktop.org/show_bug.cgi?id=95236

Do what now?  How can you apply a patch for a subsystem you don't have
responsibility for?  This is bound to cause merge conflicts.

Oh crap, I thought Linus' ack was for the mfd stuff and didn't bother
double-checking with MAINTAINTERS. Should I throw it out again and you'll
pick it up, or ok as such?

Thanks, Daniel
