[PATCH v4 0/7] ZPODD patches

[Aaron Lu <aaron.lu@amd.com>]

v4:
Rebase on top of Linus' tree, due to this, the problem of a missing
flag in v3 is gone;
Add a new function scsi_autopm_put_device_autosuspend to first mark
last busy for the device and then put autosuspend it as suggested by
Oliver Neukum.
Typo fix as pointed by Sergei Shtylyov.
Check can_power_off flag before any runtime pm operations in sr.

v3:
Rebase on top of scsi-misc tree;
Add the sr related patches previously in Jeff's libata tree;
Re-organize the sr patches.
A problem for now: for patch
scsi: sr: support zero power ODD(ZPODD)
I can't set a flag in libata-acpi.c since a related function is
missing in scsi-misc tree. Will fix this when 3.6-rc1 released.

v2:
Bug fix for v1;
Use scsi_autopm_* in sr driver instead of pm_runtime_*;

v1:
Here are some patches to make ZPODD easier to use for end users and
a fix for using ZPODD with system suspend.

Aaron Lu (7):
  scsi: sr: check support for device busy class events
  scsi: pm: add interface to autosuspend scsi device
  scsi: sr: support zero power ODD(ZPODD)
  scsi: sr: block events when runtime suspended
  scsi: pm: use runtime resume callback if available
  scsi: sr: balance sr disk events block depth
  block: genhd: add an interface to set disk's poll interval
