Note that the driver currently only exists in xenial 4.4.0 kernel so this is only being applied to xenial and artful at this time.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance!

This is looking great so far. Instance booted nicely, no signs of a
kernel panic. The driver was happily picked up in the initramfs. I'm
going to run it through some stress-ng tests to make sure everything is
fine but we're off to a good start.

As trusty can use the 4.4 kernel (via lts-xenial), this needs backporting to trusty initramfs-tools also, please.

Sponsored for trusty.
