Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
iommu: Fix two issues in iommu_copy_struct_from_user()<br />
<br />
In the review for iommu_copy_struct_to_user() helper, Matt pointed out that<br />
a NULL pointer should be rejected prior to dereferencing it:<br />

<br />
And Alok pointed out a typo at the same time:<br />
https://lore.kernel.org/all/480536af-6830-43ce-a327-adbd13dc3f1d@oracle.com<br />
<br />
Since both issues were copied from iommu_copy_struct_from_user(), fix them<br />
first in the current header.
