This was done inside the interrupt handler, but since PIO accesses are very slow this meant that a lot of time was spent inside the interrupt handler. All PIO copies are now moved to a workqueue. This should fix various issues with missing time ticks and remote key hits. Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab G%x
