In linux kernel since version 2.6.20 (release Date: 2007-02-04)
This option enables support for a dummy probing driver used to
allocated placeholder MTD devices on systems that have socketed
or removable media. Use of this driver as a fallback chip probe
preserves the expected registration order of MTD device nodes on
the system regardless of media presence. Device nodes created
with this driver will return -ENODEV upon access.
