Wysocki" , James Bottomley Cc: linux-scsi@vger.kernel.org, linux-pm@vger.kernel.org, Aaron Lu , Aaron Lu v3: Only patch 4 is modified: Remove the special case for system freeze in scsi_bus_suspend_common as pointed out by Alan Stern; Updated some comments; Removed the use of typedef (*pm_callback_t)(struct device *). v2: Change the runtime suspend behaviour of sd driver by putting the device into stopped power state. Revert 2 patches which are no longer needed as pointed out by Alan Stern. Find out device callbacks in bus callbacks as suggested by Alan Stern. Due to these changes, patch number grows from 2 -> 5. v1: The 2 patches will migrate SCSI drivers to use the pm callbacks defined in dev_pm_ops as pm_message is deprecated and should not be used by driver. Bus level callback is changed to use callbacks defined in dev_pm_ops when needed and sd's pm callback is updated to use what are defined in dev_pm_ops. Aaron Lu (5): sd: put to stopped power state when runtime suspend Revert "[SCSI] scsi_pm: set device runtime state before parent suspended" Revert "[SCSI] runtime resume parent for child's system-resume" pm: use callbacks from dev_pm_ops for scsi devices sd: update sd to use the new pm callbacks drivers/scsi/scsi_pm.c | 97 +++++++++++++++++++++++++++----------------------- drivers/scsi/sd.c | 18 +++++++--- 2 files changed, 66 insertions(+), 49 deletions(-) -- 1.7.12.21.g871e293
