The compiler thinks "conn" might be NULL after a call to hci_bind_bis(),
which cannot happen. Avoid any confusion by just making it not return a
value since it cannot fail. Fixes the warnings seen with GCC 13:
In function 'arch_atomic_dec_and_test',
inlined from 'atomic_dec_and_test' at ../include/linux/atomic/atomic-instrumented.h:576:9,
inlined from 'hci_conn_drop' at ../include/net/bluetooth/hci_core.h:1391:6,
inlined from 'hci_connect_bis' at ../net/bluetooth/hci_conn.c:2124:3:
../arch/x86/include/asm/rmwcc.h:37:9: warning: array subscript 0 is outside array bounds of 'atomic_t[0]' [-Warray-bounds=]

README
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.
