These bits are not part of the temperature: the LM70, LM71, LM74 and TMP122/TMP124 always return some of them as 1, and the TMP125 fills them with copies of the temperature LSB. Division rounds toward zero, so a negative temperature with any of these bits set is reported one LSB too high. For example, the TMP122 returns 0xffff for -0.0625 degrees C, which the driver reports as 0. The LM70 returns 0xf39f for -25 degrees C, which the driver reports as -24750. Use an arithmetic right shift instead, which drops the low bits and rounds down.
