[PATCH 1/2] HID: redragon: Fix regression in non-Redragon keyboard due to this new driver
The Redragon keyboard uses the second device being presented, but other devices with the same vendor_id/device_id pair (0x0c45:760b) use the first. Don't cause its deletion.

Right, Robert. I tested it and it works to solve the problem I reported.

The explanation is that the block you deleted was the whole reason for adding the redragon_probe function, so the changes are largely equivalent. Thanks, Robert
