Hi Martin, James,
Is there some way in this patch can be merged for 5.11 via the SCSI
tree? It has a dependency on the earlier patches in the series, now
picked up via irqchip tree. I've seen multiple rounds of SCSI pull
requests before, but not sure when we have that or if the tree is
rebased for those.
Thanks,
John
