Dear all,
Hi,I am trying to add my own device to the msm i2c bus.The s5k3c1fx and
ds2746 also connect to the same i2c bus,they work well,so I add the
driver code according to them.But it cannot transmit data.Any suggestion is
appreciated! Thank you in advance!
Here is the dmesg,my linux kernel is 2.6.32.9.
