Yes, and it loaded as well (I see it with lsmod).

However, there is no adv7175 on my board, instead it appears to have an ITT MSE3000.
There is no driver for this one (and I don't even think it is an i2c device), so
I suspect that before the driver just continued without encoder support, whereas now
it fails when it can't load the encoder.

Could that be the reason? In the absence of an encoder, I think it should just
continue, esp. since the driver doesn't use the encoder anyway.

Regards,

	Hans
