This is a note to let you know that I've just added the patch titled

USB: Add USB_QUIRK_DELAY_CTRL_MSG quirk for Corsair K70 RGB

to my usb git tree which can be found at
git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git
in the usb-linus branch.

The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.)

The patch will hopefully also be merged in Linus's tree for the next -rc kernel release.

If you have any questions about this process, please let me know.

Subject: USB: Add USB_QUIRK_DELAY_CTRL_MSG quirk for Corsair K70 RGB

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")
