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().
