[PATCH v2 0/2] pm_trace: Add locking and add sysfs attr for rechecking dev hash.

[James Hogan <james@albanarts.com>]

A fix and an improvement to the pm_trace code.

The improvement allows finding out via sysfs which device was last traced when
the device is part of a kernel module (which means it doesn't get printed on
next boot since it isn't loaded yet).

Changes in v2:
- renamed sysfs attr pm_trace_dev_hash to pm_trace_dev_match
- renamed snprint_trace_dev_hash to show_trace_dev_match
- added comment in show_trace_dev_match referring to the fact that multiple
  devices could match the hash and they all need printing out
- added documentation to Documentation/ABI/testing/sysfs-power
- minor rewording in Documentation/power/s2ram.txt

James Hogan (2):
  pm_trace: Lock pm device list mutex.
  pm_trace: Add sysfs attr for rechecking dev hash.
