v6: When user changes may_power_off flag through sysfs entry and if device is already runtime suspended, resume resume it so that it can respect this flag next time it is runtime suspended as suggested by Alan Stern. Call scsi_autopm_get/put_device once in sr_check_events as suggested by Alan Stern. v5: Add may_power_off flag to scsi device. Alan Stern suggested that I should not mess runtime suspend with runtime power off, but the current zpodd implementation made it not easy to seperate. So I re-wrote the zpodd implementation, the end result is, normal ODD can also enter runtime suspended state, but their power won't be removed. 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.
