There are probably better places to spend your time!

If you want 'security' for kmalloc() then:

#define KMALLOC_TYPE(flags) (type *)kmalloc(sizeof (type), flags)
#define KMALLOC(ptr, flags) *(ptr) = KMALLOC_TYPE(typeof *(ptr), flags)

and change:
	ptr = kmalloc(sizeof *ptr, flags);
to:
	KMALLOC(&ptr, flags);

But it is all churn for churn's sake.
