The fix has long since been submitted and is available in linux-next.

 From my notes:

Fix posted at
https://patchwork.kernel.org/project/linux-media/patch/0f536cd8-01db-5d16-2cec-ec6d19409a49@xs4all.nl/
and in linux-next as commit 3c5412cdec9f ("pinctrl-sunxi:
sunxi_pinctrl_gpio_direction_in/output: use correct offset").
The fix exposes a lockdep splat for which a fix is posted at
https://lore.kernel.org/lkml/20220216040037.22730-1-samuel@sholland.org/
This patch is available in linux-next as commit 4649b97042c3 ("pinctrl:
