./drivers/media/video/buz.c: *   If the requested buffer size is smaller than KMALLOC_MAXSIZE,

Doing at least a "christmas tree" build ("all lights on", though in
this case "build *everything* that can be built as a module, and use
the config defaults for the rest" would be quite enough to catch
these) before it goes out the door would be useful...
