And while we are at it: Could you also try replacing
i2c_write() with i2c_smbus_write_byte_data(isp1301_i2c_client,
reg, val)?
Interestingly now, replacing i2c_write() calls with 
i2c_smbus_write_byte_data() did _not_ work (hardware
initialization failure). I guess this is due to the differences
between i2c and smbus, and the hardware only handles the former
correctly?
Did you take into consideration that the smbus-call has (client,
reg, val) as arguments while i2c_write has (val, reg), that is you
have to swap the arguments?
Yes, that's it! :-)

I'll update my patch to not use i2c_write() anymore.

For the remaining i2c_write() in the current kernel driver, I will
include an additional patch to remove it completely in favour of
i2c_smbus_write_byte_data().

Thanks,

Roland
