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