In the Linux kernel, the following vulnerability has been resolved: media: hi846: fix usage of pm_runtime_get_if_in_use() pm_runtime_get_if_in_use() does not only return nonzero values when the device is in use, it can return a negative errno too. And especially during resuming from system suspend, when runtime pm is not yet up again, -EAGAIN is being returned, so the subsequent pm_runtime_put() call results in a refcount underflow. Fix system-resume by handling -EAGAIN of pm_runtime_get_if_in_use().
