Subject: [power] Fixup device suspend/resume function names.
X-Git-Tag: v2.6.0-test4~27
X-Git-Url: http://git.neil.brown.name/?a=commitdiff_plain;h=9234878aafa9a6e8f595fa259ea4fe267526714c;p=history.git

[power] Fixup device suspend/resume function names.

- Revert names of functions back to device_{suspend,resume} since at least
  APM are still using them.
