UBUNTU: SAUCE: hid: ntrig: zero-initialize ntrig struct
Setting zeros using kzalloc instead.
Has been tested succesfully on Dell Studio 17, Dell XT2, HP TX2 and
Lenovo T410s. Not likely to go upstream in its present form. However,
it does help constitue a tuning-free driver which works well together
with Unity, and as such are vital to the MT push.
