3.16.61-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Nico Sneck <snecknico@gmail.com>

commit bba57eddadda936c94b5dccf73787cb9e159d0a5 upstream.

Corsair Strafe appears to suffer from the same issues
as the Corsair Strafe RGB.
Apply the same quirks (control message delay and init delay)
that the RGB version has to 1b1c:1b15.

With these quirks in place the keyboard works correctly upon
booting the system, and no longer requires reattaching the device.
