Add NULL tests on various calls to kzalloc and devm_kzalloc. The semantic match that finds these problems is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression x,y; identifier fld; @@ ( x = \(vmalloc\|kmalloc\|kzalloc\|kcalloc\|kmem_cache_alloc\|krealloc\| kmemdup\|kstrdup\| devm_kzalloc\|devm_kmalloc\|devm_kcalloc\|devm_kasprintf\| kmalloc_array\)(...,<+... __GFP_NOFAIL ...+>,...); | * x = \(vmalloc\|kmalloc\|kzalloc\|kcalloc\|kmem_cache_alloc\|krealloc\| kmemdup\|kstrdup\| devm_kzalloc\|devm_kmalloc\|devm_kcalloc\|devm_kasprintf\| kmalloc_array\)(...); ) ... when != (x) == NULL when != (x) != NULL when != (x) == 0 when != (x) != 0 when != x = y ( x->fld | *x | x[...] ) // </smpl> --- drivers/s390/char/con3215.c | 2 ++ drivers/s390/char/raw3270.c | 2 ++ sound/soc/fsl/imx-pcm-dma.c | 2 ++ sound/soc/intel/baytrail/sst-baytrail-pcm.c | 2 ++ sound/soc/omap/omap-hdmi-audio.c | 2 ++ 5 files changed, 10 insertions(+) -- To unsubscribe from this list: send the line "unsubscribe kernel-janitors" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
