wondering if the struct device of the DS90UB913 could be passed instead
of the port, to avoid passing the port throught
ds90ub9xx_platform_data.
Interesting thought. That would limit the number of remote i2c busses to one, though. Not a problem for FPD-Link, but I wonder if that's assuming too much for the future users. Then again, this is an in-kernel API so we could extend it later if needed. So I'll try this out and see if I hit any issues.
