> RTL8822CU, RTL8822BU, and RTL8821CU need an extra register write after
> reading and writing certain addresses.
>
> Without this, the firmware upload fails approximately more than 50% of
> the time.
>
> Tested with RTL8811CU (Tenda U9 V2.0) which is the same as RTL8821CU
> but without Bluetooth.
>
> Fixes: a82dfd33d123 ("wifi: rtw88: Add common USB chip support")
