Boris Brezillon 1530578abd mtd: Avoid probe failures when mtd->dbg.dfs_dir is invalid
Commit e8e3edb95c ("mtd: create per-device and module-scope debugfs
entries") tried to make MTD related debugfs stuff consistent across the
MTD framework by creating a root <debugfs>/mtd/ directory containing
one directory per MTD device.

The problem is that, by default, the MTD layer only registers the
master device if no partitions are defined for this master. This
behavior breaks all drivers that expect mtd->dbg.dfs_dir to be filled
correctly after calling mtd_device_register() in order to add their own
debugfs entries.

The only way we can force all MTD masters to be registered no matter if
they expose partitions or not is by enabling the
CONFIG_MTD_PARTITIONED_MASTER option.

In such situations, there's no other solution but to accept skipping
debugfs initialization when dbg.dfs_dir is invalid, and when this
happens, inform the user that he should consider enabling
CONFIG_MTD_PARTITIONED_MASTER.

README

Linux kernel
============

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
