It has been pointed out that the kernel log messages warning about problems in USB configuration and related descriptors are vexing for users. The warning log level has a fairly high priority, but the user can do nothing to fix the underlying errors in the device's firmware. To reduce the amount of useless information produced by tools that filter high-priority log messages, we can change these warnings to notices, i.e., change dev_warn() to dev_notice(). The same holds for a few messages that currently use dev_err(): Unless they indicate a failure that might make a device unusable (such as inability to transfer a config descriptor), change them to dev_notice() also.

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.
