ASoC: omap-hdmi-audio: add NULL test
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; identifier fld; @@ * x = devm_kzalloc(...); ... when != x == NULL x->fld // </smpl> Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Acked-by: Peter Ujfalusi <peter.ujfalusi@ti.com> Signed-off-by: Mark Brown <broonie@kernel.org>
