  The code to select isp_dev->formats[] is overly complicated.  We can
just use the "pad" as the index.  This will making adding new pads
easier in future patches.  No functional change.

I'm not sure that patchwork will find this patch if it doesn't have
[PATCH] in the subject...  But otherwise the patch looks good.  Thanks!

Linux-media uses patchwork, so probably it was missed because it didn't
have a [PATCH] in the subject.  Just resend.
