[ Upstream commit e4debea9be7d5db52bc6a565a4c02c3c6560d093 ]
The normal path of the function makes the assumption that 'pm_ops->core_power' may be NULL. We should make the same assumption in the error handling path or a NULL pointer dereference may occur.
Add the missing test before calling 'pm_ops->core_power'
