thunderbolt: Correct the size argument to devm_kzalloc
nhi->rx_rings does not have type as struct tb_ring *, as it is a double pointer so the elements of the array should have pointer type, not structure type. The Coccinelle semantic patch that makes this change is as follows: // <smpl> @disable sizeof_type_expr@ type T; T **x; @@ x = <+...sizeof( - T + *x )...+> // </smpl> Signed-off-by: Himangi Saraogi <himangi774@gmail.com> Acked-by: Julia Lawall <julia.lawall@lip6.fr> Cc: Andreas Noever <andreas.noever@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
