As promised, please fix the updated patch. Please note that there are 2
patches, one for linux HEAD and one for 4.19. I had to make two patches
as there are changes in HEAD not present in 4.19. btw, your version of
the 4.19 patch is possibly broken with OF platforms, that's why your
patches and mine are different. For your case on orion5x, it should not
make any difference.
