139It contains the following fields:
140
141* ops:
142 Pointer to device operations.
143* info:
144 NULL-terminated list of device channel descriptors.

238 The HWMON_CHANNEL_INFO() macro can and should be used when possible.
239 With this macro, the above example can be simplified to
240
233 &lm75_chip,
234 &lm75_temp,
235 NULL
