I noticed that it was lacking and applied cleanly on 5.4.  As of
5.4.25 it's still not stable there.  I only noticed it because I was
comparing all the patches in mainline in "net/qrtr" with what we had
in our tree and stumbled upon this one.

Looking at it a little more carefully, I guess you could say:

Fixes: e7044482c8ac ("net: qrtr: Pass source and destination to
enqueue functions")

...though it will be trickier to apply past commit 194ccc88297a ("net:
qrtr: Support decoding incoming v2 packets") just because the math
changed.
