strnchr takes arguments in the order of its name: string, max bytes to read, character to search for. Here we're passing '\n' aka 10 as the buffer size, and searching for sizeof(buf) aka BRCMF_DCMD_SMLEN aka 256 (aka '\0', since it's implicitly converted to char) within those 10 bytes. Just interchanging the last two arguments would still leave a bug, because if we've been successful once, there are not sizeof(buf) characters left after the new value of p. Since clmver is immediately afterwards passed as a %s argument, I assume that it is actually a properly nul-terminated string. For that case, we have strreplace().

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
