Hi Danny,

Thank you for all your work bringing this through so many revisions, and
I am glad to help by testing it.

I tested this on an AST2600-based OpenBMC platform (NVIDIA Vera Rubin)
that has several CP2112s. With this patch, a CP2112 whose device-tree
"i2c" subnode declares downstream I2C devices (PCA9555 expanders) has
them auto-instantiated by i2c-core: they appeared on the adapter's I2C
bus with their gpio-line-names. CP2112s with an empty "i2c" node
registered their adapters but instantiated no children, as expected.
