Hi,
it looks to me like the rockchip_i2c_xfer function returns 0 if
everything was successful, but shouldn't the i2c master_xfer functions
return the number of messages actually processed?
I was just wondering about reading sources and can't do real world
testing due to lack of hardware...

I think you're right. I tested this only with the RK808 PMIC on the Nano Pi N10
and noticed no problems, but it seems that was just me being lucky.
I'll give it a test with fixed return value and send a patch in the
coming days.
Thanks for the review!
Cheers,
Ahmad
