Build bot detects that err may be returned uninitialized in
devlink_fmsg_prepare_skb(). This is not really true because
all fmsgs users should create at least one outer nest, and
therefore fmsg can't be completely empty.
That said the assumption is not trivial to confirm, so let's
follow the bots advice, anyway.
This code does not seem to have changed since its inception in
commit 1db64e8733f6 ("devlink: Add devlink formatted message (fmsg) API")

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.
