Hi Martin,

Recently it was reported that patch "scsi: core: pm: Rely on the device driver
core for async power management" causes resuming to take longer if an ATA disk
is present. This patch series fixes that regression. Please consider this
patch series for kernel v5.20.

Thanks,

Bart.

Changes compared to v1: addressed John Garry's two comments.

Bart Van Assche (2):
  scsi: core: Move the definition of SCSI_QUEUE_DELAY
  scsi: sd: Rework asynchronous resume support
