Was this patch possibly missed from 5.10.y ?

Also, while at it, I think it might make sense to pick the following two 
patches as well, they dramatically reduce interrupt rate of the RSI WiFi 
device, so it stops overloading lower-end devices:
287431463e786 ("rsi: Move card interrupt handling to RX thread")
abd131a19f6b8 ("rsi: Clean up loop in the interrupt handler")
