__dev_alloc_name() handles both the sprintf and non-sprintf target names. This complicates the code. dev_prep_valid_name() already handles the non-sprintf case, before calling __dev_alloc_name(), make the only other caller also go thru dev_prep_valid_name(). This way we can drop the non-sprintf handling in __dev_alloc_name() in one of the next changes. commit55a5ec9b77("Revert "net: core: dev_get_valid_name is now the same as dev_alloc_name_ns"") and commit029b6d1405("Revert "net: core: maybe return -EEXIST in __dev_alloc_name"") tell us that we can't start returning -EEXIST from dev_alloc_name() on name duplicates. Bite the bullet and pass the expected errno to dev_prep_valid_name(). dev_prep_valid_name() must now propagate out the allocated id for printf names.

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.
