It does something with threading... lock/unlock... and actually as it is (only) needed for hisi boxes it looks more than a work-a-round to fix driver issues... (other boxes don't have that issue - maybe hisi experienced it because it is too fast )...
The patch as it is now is actually a kind of if box x then do y fix.... ...
But still when it also might have improvements with other boxes maybe that lock/unlock stuff might also be an improvement for something other boxes might have also the issue, but it is never triggered....If so then we might also consider/test if the if hisi box test could be removed also... If we accept it...!
