FROMLIST: driver: bluetooth:btusb: Allow firmwarea re-download when version matches
typo s/firmwarea/firmware . upstream submission does not have this issue.
…rsion matches Since USB can disconnect at any time, if it disconnects during the BT firmware download, the BT controller firmware version may still be updated even without completing the download. When USB reconnects, the BT host detects the same version as in the firmware file, which prevents the firmware from being downloaded again. Therefore, remove the equality check to ensure that after USB reconnection, the BT host can still download the firmware.
