Subject: [PATCH 3.16 152/305] usb: quirks: Add delay-init quirk for
 Corsair K70 LUX RGB

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

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

From: Emmanuel Pescosta <emmanuelpescosta099@...il.com>

commit a77112577667cbda7c6292c52d909636aef31fd9 upstream.

Following on from this patch: https://lkml.org/lkml/2017/11/3/516,
Corsair K70 LUX RGB keyboards also require the DELAY_INIT quirk to
start correctly at boot.

Dmesg output:
usb 1-6: string descriptor 0 read error: -110
usb 1-6: New USB device found, idVendor=1b1c, idProduct=1b33
usb 1-6: New USB device strings: Mfr=1, Product=2, SerialNumber=3
usb 1-6: can't set config #1, error -110
