[ Upstream commit86d884f528] In various places, string buffers of a fixed size are allocated, and filled using snprintf() with the same fixed size, which is error-prone. Replace this by calling devm_kasprintf() instead, which always uses the appropriate size. While at it, remove an unneeded intermediate variable, which allows us to drop a cast as a bonus. With the initial behavior it would have been possible to have a device tree with a node address that would make "ccc<node_address>_pll<N>" exceed 18 characters. If that happened, the <N> would be cut off & both pll 0 & 1 would be named identically. If that happens, pll1 would fail to register. Thus, the fixes tag has been added to this commit.

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.
