This is more likely to annoy than to help users of embedded distros where
this driver is enabled by default. Making the blockdevs available does
not imply that they are in use, and warning about bootloader partitions
or other devices which obviously never will be mounted is more confusing
than helpful.
Move the warning to open(), where it will be of more use - actually warning
anyone who mounts a file system on NAND using mtdblock.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
