Subject[PATCH 4.20 26/57] USB: Add USB_QUIRK_DELAY_CTRL_MSG quirk for Corsair K70 RGB
Date
4.20-stable review patch.  If anyone has any objections, please let me know.

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

From: Jack Stocker <jackstocker.93@gmail.com>

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")
