clang static analysis reports this problem
hci_sync.c:4428:2: warning: Undefined or garbage value
returned to caller
return err;
^~~~~~~~~~
If there are no connections this function is a noop but
err is never set and a false error could be reported.
Return 0 as other hci_* functions do.

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.
