This is usually good if the #defines give a meaning to the opaque magic numbers. However in this case, the semantic meaning is inherent in the name of the C99-addressable fields, and that means duplication of information, and only makes the code hard to maintain since you every time have to add a new #define AND update the site where it is to be used. Get rid of the #defines and just open code the values into the appropriate struct elements. Make sure to explicitly address the .hz and .value fields in the st_sensor_odr_avl struct so that the meaning of all values is clear. This patch is purely syntactic should have no semantic effect.
