Subject: PM: hibernate: Do not initialize error in snapshot_write_next()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=4ac934b1aaa99e00ca25875d55094a4fe34e212d;p=linux.git

PM: hibernate: Do not initialize error in snapshot_write_next()

The error variable in snapshot_write_next() gets a value before it is
used, so don't initialize it to 0 upfront.
