[PATCH v6 0/5] hwmon: (pmbus/acbel-fsg032) Add Acbel power supply

[Lakshmi Yadlapati]

Adding new acbel,fsg032 driver and documentation updates.

Changes since V5:
Add symlink from manufacturer serial number to ccin since ccin is not
available in acbel-fsg032 power supply driver.

Lakshmi Yadlapati (5):
  dt-bindings: vendor-prefixes: Add prefix for acbel
  dt-bindings: trivial-devices: Add acbel,fsg032
  hwmon: (pmbus/acbel-fsg032) Add Acbel power supply
  docs: hwmon: Add documentaion for acbel-fsg032 PSU

There is no such hwmon requirement (hwmon neither knows nor
cares about "ccin"), and this is not a valid multi-line comment.
Please drop this change.

If some userspace code is looking for a debugfs file named "ccin",
change it to read "mfr_serial" instead of "ccin" if "ccin" is
not available. Hacking a kernel driver to meet some arbitrary
userspace requirement is not acceptable.

Thanks,
Guenter
