Some static checker run by 0day reports a variableScope warning.
net/bluetooth/smp.c:870:6: warning:
The scope of the variable 'err' can be reduced. [variableScope]
There is no need for two separate variables holding return values.
Stick with the existing variable. While at it, don't pre-initialize
'ret' because it is set in each code path.
tk_request() is supposed to return a negative error code on errors,
not a bluetooth return code. The calling code converts the return
value to SMP_UNSPECIFIED if needed.
Fixes: 92516cd97f ("Bluetooth: Always request for user confirmation for Just Works")

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.
