Notes:
 jmm> Unclear, might affect drivers/amba in some way?
 bwh> The Android bulletin links to a patch for PCI that *wasn't*
 bwh> applied upstream (and isn't needed), but based on the
 bwh> description as "AMBA driver" I found what I think is the actual
 bwh> upstream fix.
 bwh> Introduced in Linux 4.0 by commit 3cf385713460 "ARM: 8256/1:
 bwh> driver coamba: add device binding path 'driver_override'".
 carnil> There was possibly intiial confusion re CVE-2018-9415 and
 carnil> the second assigned CVE-2018-9385 which are related.
