Andrew, this kinda of implementation is really hard to get in a fast review, 
fortunately I happen to be testing one lan743x board with a 5.10.79 kernel
that had the new locks in place, and noticed that really fast, but I wrongly 
assumed that call was okayish since the driver was on stable.
If you need to do some testing I will still have the hardware with me for 
some time.
