This combination (the diff and this HID patch) works on top of v5.7.

I tried also these other combinations:

v5.7
- HID patch + this diff -> ok
- HID patch -> not ok
- HID + acked i2c-dw patch -> acked i2c-dw patch doesn't apply

v5.8-rc3
- acked i2c-dw patch -> ok
- HID patch -> nok
- HID patch + acked i2c-dw patch -> nok
- HID patch + this diff -> diff doesn't apply

Hopefully gives some glue. I'll be out of office for a few weeks and 
unfortunately cannot test patches meanwhile.
