misc: cxl: 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> Acked-by: Andrew Donnellan <ajd@linux.ibm.com> Link: https://lore.kernel.org/r/1577634178-22530-2-git-send-email-Julia.Lawall@inria.fr Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
