PM / Suspend: Off by one in pm_suspend()
commit 528f7ce6e439edeac38f6b3f8561f1be129b5e91 upstream. In enter_state() we use "state" as an offset for the pm_states[] array. The pm_states[] array only has PM_SUSPEND_MAX elements so this test is off by one. Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Rafael J.
