Is there a reason you need to do this fixup? Based on your commit
message its unclear if this patch is really needed...

If you are going to do this fixup, av_ should not be initialized with
values (you're currently doing the same initialization 2 times). In
general, we could probably shave a bit off of U-Boot's size by leaving
av_ uninitialized and implementing your manual calculation of av_ above,
but I'm not sure why this change should be included in this patch
series.

Best,
