Johan Hovold 3bbbcafb0d regulator: core: fix debugfs creation regression
commit 2a4b49bb58123bad6ec0e07b02845f74c23d5e04 upstream.

regulator_get() may sometimes be called more than once for the same
consumer device, something which before commit dbe954d8f163 ("regulator:
core: Avoid debugfs: Directory ...  already present! error") resulted in
errors being logged.

A couple of recent commits broke the handling of such cases so that
attributes are now erroneously created in the debugfs root directory the
second time a regulator is requested and the log is filled with errors
like:

	debugfs: File 'uA_load' in directory '/' already present!
	debugfs: File 'min_uV' in directory '/' already present!
	debugfs: File 'max_uV' in directory '/' already present!
	debugfs: File 'constraint_flags' in directory '/' already present!

on any further calls.

Fixes: 2715bb11cfff ("regulator: core: Fix more error checking for debugfs_create_dir()")
Fixes: 08880713ceec ("regulator: core: Streamline debugfs operations")

README

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.
