[PATCH 65/88] hwmon: (pmbus/ltc2978) Use detected chip ID to select supported functionality

Thu Mar 14 10:35:58 UTC 2013 -stable review patch.  If anyone has any objections, please let me know.


From: Guenter Roeck <linux at roeck-us.net>

commit f366fccd0809f13ba20d64cae3c83f7338c88af7 upstream.

We read the chip ID from the chip, use it to determine if the chip ID provided
to the driver is correct, and report it if wrong. We should also use the
correct chip ID to select supported functionality.
