[RFC][PATCH -mm 6/9] PM: Fix compilation of suspend code if CONFIG_PM is unset

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

 



From: Rafael J. Wysocki <rjw@xxxxxxx>

Some platforms, particualrly in the ARM tree, require that suspend_set_ops() and
pm_suspend() be defined even if CONFIG_PM is not set.  Make this requirement be
satisfied.
