Hi,

I am having trouble using iic_smbus_quick() of i2c/busses/i2c-ibm-iic.c
I am trying to i2c_probe() to probe for some devices, which at the end
calls iic_smbus_quick().

Basically, I get a Data Machine Check as soon as iic->directcntl is
accessed. Actually, this register is not described in the (old)
documentation I have.
Is anybody using this successfully on STB04?


Greets,
Andre'
