Drivers can return -ENODEV or -ENXIO from their probe to reject a device match, and return -EPROBE_DEFER if probe should be retried. Any other error code is not expected during normal behavior and indicates an issue occurred, so it should be logged at the error level. Also make use of the device variant, dev_err(), so that the device metadata is attached to the log message. Signed-off-by: "Nícolas F. R. A.

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.
