FWIW:
Tested-by: Benjamin Tissoires <bentiss@kernel.org>

I've tested Danny's series + my SSDT override, with and without your
series on top of the master of hid.git (v6.4+merge of the hid.git tree
for v6.5-rc1), and in both cases, I can access the I2C-HID node that
sits on top of the CP2112 USB adapter.

Cheers,
Benjamin
