The author of this driver clearly wasn't familiar with the BMIDE specification
(also known as SFF-8038i) when he implemented the bmdma_status() method: first,
the interrupt bit of the BMIDE status register corresponds to nothing else but
INTRQ signal (ATAPI_DEV_INT here); second, the error bit is only set if the
controller encounters issue doing the bus master transfers, not on the IDE DMA
burst termination interrupts like here (moreover, setting the error bit doesn't
cause an interrupt). We now need to disable all those unused interrupts...(The only thing I couldn't figure out is how to flush the FIFO to memory once
the interrupt happens as required by the mentioned spec.)Signed-off-by: Sergei Shtylyov

[Patch description from Alan Stern]
If a child device was runtime-suspended when a system suspend began,
then there will be nothing to prevent its parent from
runtime-suspending as soon as it is woken up during the system resume.
Then when the time comes to resume the child, the resume will fail
because the parent is already back at low power.On the other hand, there are some devices which should remain at low
power across an entire suspend-resume cycle. The details depend on the
device and the platform.This suggests that the PM core is not the right place to solve the
problem. One possible solution is for the subsystem or device driver
to call pm_runtime_get_sync(dev->parent) at the start of the
system-resume procedure and pm_runtime_put_sync(dev->parent) at the
end.Acked-by: Alan Stern
