Missing firmware files

[Andrew Worsley <amworsley@gmail.com>]

After the latest upgrade of buster I get this list of missing files
when it rebuilt my initramfs. The files are not in my current
firmware-misc-nonfree 20190114-1

I don't know where they might be found - or how important they are.

My suspend to ram is no longer working - I wondering if this is
related but this is a troublesome MacBookPro10,1 with regard to
hibernating so it my be unrelated.

Thanks for any suggestions

Andrew
