└─> Exclude Staging drivers from being built

Are you sure you really want to build the staging drivers?
They taint your kernel, don't live up to the normal Linux
kernel quality standards, are a bit crufty around the edges,
and might go off and kick your dog when you aren't paying
attention.

Say N here to be able to select and build the Staging drivers.
This option is primarily here to prevent them from being built
when selecting 'make allyesconfg' and 'make allmodconfig' so
don't be all that put off, your dog will be just fine.
