vfio/spapr_tce: use mmgrab
Mmgrab was introduced in commit f1f1007644ff ("mm: add new mmgrab() helper") and most of the kernel was updated to use it. Update a remaining file. The semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/) <smpl> @@ expression e; @@ - atomic_inc(&e->mm_count); + mmgrab(e); </smpl> Signed-off-by: Julia Lawall <Julia.Lawall@inria.fr> Reviewed-by: Cornelia Huck <cohuck@redhat.com> Signed-off-by: Alex Williamson <alex.williamson@redhat.com>
