Subject: [PATCH v2 0/2] hwmon: (pmbus/core) Add lock and unlock functions

Debugfs operations may set the page number, which must be done
atomically with the subsequent i2c operation. Lock the update_lock
in the debugfs functions and provide a function for pmbus drivers
to lock and unlock the update_lock.
Use the new lock/unlock functions in the ibm-cffps driver and make
some additional improvements.

Changes since v1:
 - No whitespace change in cffps patch.

Eddie James (2):
  hwmon: (pmbus/core) Add lock and unlock functions
  hwmon: (pmbus/ibm-cffps) Use default debugfs attributes and lock
    function
