Thanks for the update Ondrej. It seems that the patch may be in place. Since I've updated my Fedora 30 system's kernel to 5.1.6, I haven't had to run dracut to rebuild my initramfs. The raven_dmcu.bin file remains renamed as raven_dmcu.bin.old. Previously, I've had to move/rename the file and run dracut every time a kernel update came out.
