    9595* gl518sm: Assume that new values are close to old values, so start with 
    9696  trying to use a small range near the old values (already partially done) 
    97 * lm77: Add detection in lm75.c and sensors-detect to distinguish from 
    98   an lm75. Add support for the two new registers. 
    9997* Add MTP006F chip: http://www.myson.com/Pcd/MTP006/Mtp006.pdf

    73 and the two additional registers in the LM77 are not supported.

     75The LM77 is not supported, contrary to what we pretended for a long time. 
     76Both chips are simply not compatible, value encoding differs.
