* An explanation from kayork@mail.utexas.edu:
*
* During I2C reads, the KS0127 only samples for a stop condition
- * during the place where the acknoledge bit should be. Any standard
+ * during the place where the acknowledge bit should be. Any standard
* I2C implementation (correctly) throws in another clock transition
* at the 9th bit, and the KS0127 will not recognize the stop condition
* and will continue to clock out data.
*
* So we have to do the read ourself. Big deal.
