Failed module installations with updated kernel 3.16.7-24

linux v3.16.7-21-desktop x86_64
While browsing the log file from the latest system update, the following output caused me some concern, especially since I have no idea if it is significant. The “failed” modules would seem to be rather important, like the USB drivers; yet the system functions as expected, USB and all.

What are the consequences of the failed installations, if any?

Ignore that.
Those modules are built into the kernel and therefore cannot (and need not) be added to the initrd.
dracut is just more verbose in this regards since a while.

Good. One less thing to worry about.
