In linux kernel since version 2.6.28 (release Date: 2008-12-24)  
This option allows you to select a number of drivers that are
not of the "normal" Linux kernel quality level. These drivers
are placed here in order to get a wider audience to make use of
them. Please note that these drivers are under heavy
development, may or may not work, and may contain userspace
interfaces that most likely will be changed in the near

Using any of these drivers will taint your kernel which might
affect support options from both the community, and various
commercial support organizations.

If you wish to work on these drivers, to help improve them, or
to report problems you have with them, please see the
driver_name.README file in the drivers/staging/ directory to
see what needs to be worked on, and who to contact.

If in doubt, say N here.
