Linux kernel source tree
08880713ce
If CONFIG_DEBUG_FS is not set:
regulator: Failed to create debugfs directory
...
regulator-dummy: Failed to create debugfs directory
As per the comments for debugfs_create_dir(), errors returned by this
function should be expected, and ignored:
* If debugfs is not enabled in the kernel, the value -%ENODEV will be
* returned.
*
* NOTE: it's expected that most callers should _ignore_ the errors returned
* by this function. Other debugfs functions handle the fact that the "dentry"
* passed to them could be an error and they don't crash in that case.
* Drivers should generally work fine even if debugfs fails to init anyway.
Adhere to the debugfs spirit, and streamline all operations by:
1. Demoting the importance of the printed error messages to debug
level, like is already done in create_regulator(),
2. Further ignoring any returned errors, as by design, all debugfs
functions are no-ops when passed an error pointer.

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.
