PCI: Use scnprintf(), not snprintf(), in sysfs "show" functions Sysfs "show" methods should return the number of bytes printed into the buffer. This is the return value of scnprintf() [1]. snprintf(buf, size, ...) prints at most "size" bytes into "buf", but returns the number of bytes that *would* be printed if "buf" were large enough. Replace use of snprintf() with scnprintf(). No functional change intended.
