Arnd Bergmann c3b69f0fda caif: reduce stack size, again
[ Upstream commit b630c781bcf6ff87657146661816d0d30a902139 ]

I tried to fix the stack usage in this function a couple of years ago,
but there is still a problem with the latest gcc versions in some
configurations:

net/caif/cfctrl.c:553:1: error: the frame size of 1296 bytes is larger than 1280 bytes [-Werror=frame-larger-than=]

Reduce this once again, with a separate cfctrl_link_setup() function that
holds the bulk of all the local variables. It also turns out that the
param[] array that takes up a large portion of the stack is write-only
and can be left out here.

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.
