[PATCH] PM/Hibernate: Enable usermodehelpers in hibernate() error path

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]


If create_basic_memory_bitmaps() fails, usermodehelpers are not re-enabled
before returning. Fix this. And while at it, reword the goto labels so that
they look more meaningful.
