--- Comment #35 from Deepak M <m.deepak at intel.com> ---
i2c errors exists both in working and non working logs. As far as i remember
the i2c elements were used for backlight on/off sequence in BYT. So can you
please confirm when the display is blank are you able to see the backlight ?

Also the bus number what we were using was 3, can you please try to hardcode
the value of 3 for the bus number in the mipi_exec_i2c() and give a try.
