Hey, 

Here is exactly the same on an ASUS T304UA. This is the same webcam with the same error. I tried to skip the check of the clock frequency in the code. However it returns an error on the "fwnode_graph_get_next_endpoint".
I don't have enough time to check the code but it seems that it tries to initialize the wrong I2C device no?

No changes on Linux 5.9rc6.
