In my whole I2C life, I have neither seen a target supporting 10-bit
addressing nor a a system that uses 10-bit addressing. I am even tempted
to remove support from the kernel omce in a while. If the support is
broken in this driver, it can be removed. A working version (if
possible) can be added again by someone who needs it. I am taking bets
it will be "never". Besides, the driver never set I2C_FUNC_10BIT_ADDR,
so it really shouldn't have been used anywhere.
