commit 3483254b89438e60f719937376c5e0ce2bc46761 upstream.
To match the Corsair Strafe RGB, the Corsair K70 RGB also requires USB_QUIRK_DELAY_CTRL_MSG to completely resolve boot connection issues discussed here: https://github.com/ckb-next/ckb-next/issues/42. Otherwise roughly 1 in 10 boots the keyboard will fail to be detected.
Patch that applied delay control quirk for Corsair Strafe RGB: cb88a0588717 ("usb: quirks: add control message delay for 1b1c:1b20")
Previous K70 RGB patch to add delay-init quirk: 7a1646d92257 ("Add delay-init quirk for Corsair K70 RGB keyboards")
