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>
