Add NULL test on call to devm_kzalloc. The semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression x; @@ * x = devm_kzalloc(...); ... when != x == NULL *x // </smpl> Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> --- sound/soc/fsl/imx-pcm-dma.c | 2 ++ 1 file changed, 2 insertions(+)
