[lm-sensors] [PATCH v2 0/4] hwmon: (pmbus) Updates for ADM1275/ADM1276

[Guenter Roeck]

The following two patches improve support for ADM1275 and add support for
ADM1276.

v2:
- Added patch to document internal API in more detail.
- Added patch changing pmbus_do_remove() from returning an int to void.
- Replaced error return code EINVAL with ENXIO as this is more appropriate.
- Validate page number in adm1275_read_byte_data() and return error if the page
  is non-zero.
