Browse Source 
The per-device option selection is a feature that some
developers love, while others hate...

So, let's make both happy by making it optional.

Configuring the media subsystem can be complex, as there are
hundreds of drivers and other config options.
This menu offers option that will help the Kernel's config
system to hide drivers that are out of the scope of the
user needs, and disabling core support for unused APIs.
If not selected, all non-optional media core functionality
needed to support media drivers will be enabled. Also, all
media device drivers should be shown.
