From: Bill Wendling <[email protected]> Similar to bfa_fcs_fabric_nsymb_init(), bfa_fcs_fabric_psymb_init() builds the port symbolic name using strscpy() and a chain of seven or eight strlcat() calls.
In preparation for removing the deprecated strlcat() API[1], replace the chained strscpy() and strlcat() calls with a single snprintf() call. An empty host_os_patch naturally contributes no characters through %s, allowing both cases to be handled by the same snprintf() call. Since snprintf() also NUL-terminates the destination, the explicit final NUL assignment can be dropped.
