kemal did a ton of work on the driver trying to get 7260 to work,
without success.  The firmware errors made no sense and it was
impossible to understand where the issue was.  I don't remember if his
latest patch was merged or not, I believe that it's floating on the ml
from around august last year, but again, no dice.  If anyone wants to
stare at it some more, I suggest looking at his mails and diffs.  I
remember I helped test it with a 7260 (x240) and with my t490s' i219-v
with similar results.
