Subject: [PATCH 4.14 044/117] USB: Add USB_QUIRK_DELAY_CTRL_MSG and USB_QUIRK_DELAY_INIT for Corsair K70 RGB RAPIDFIRE

From: Jonathan Cox <jonathan@...ox.net>

commit be34a5854b4606bd7a160ad3cb43415d623596c7 upstream.

The Corsair K70 RGB RAPIDFIRE needs the USB_QUIRK_DELAY_INIT and
USB_QUIRK_DELAY_CTRL_MSG to function or it will randomly not
respond on boot, just like other Corsair keyboards
