More Context

When running the following piece of code:

processor = AutoProcessor.from_pretrained("microsoft/git-base")
encoding = processor(images=Image.open("Cat.jpg"), text="A cute cat.", padding="max_length")

I observed a similar warning message ("unused or unrecognized kwargs: padding") in issue#30106, which is nicely fixed by PR#30905.

So, I tried to fix the same problem for this processing_git.py file and now it works without the warning message.

Other Thought

This looks like a common problem in multiple processors. Probably similar updates are also needed for other ones.

Thanks!

@Eric2i Great thanks for the details! There's actually a big PR which will be merged in soon which should address this (and many other difficulties with processor kwargs!) #30511
