Also notable is the
continued slow climb by
companies such as TI
and Samsung [….]
Contributions by Linaro
assignees are normally
credited back to their
home companies.
Nonetheless, Linaro
makes an appearance
on its own here as a
result of the work of an
increasing number of
engineers employed by
[Linaro] itself.
