The BYTECNT register holds the transfer size minus one. Setting it to the correct value removes the need for a dummy read/write at the end of each transfer. As zero-length transfers are not supported, do not advertise I2C_FUNC_SMBUS_QUICK. In other words, this patch makes the driver transfer the number of bytes requested unless this is zero, which is not supported by the hardware and is thus refused.
