I came across this code:

         struct mcp23s08_driver_data     *data;
	...
	data = kzalloc(sizeof *data + chips * sizeof(struct mcp23s08),
                         GFP_KERNEL);


Since data wasn't initialized when `sizeof *data' is called, wasn't this a non-initialized pointer dereference?

Cheers
