I'm using evaluation boards with various Analog Devices chips over
parallel port. The bus driver being based on i2c-algo-bit, I assume that
it does rely on i2c_smbus_xfer_emulated? And it happens that everything
always worked OK, including writes, so how could there be such an
important bug in there?
