Damien Le Moal 0c76106cb9 scsi: sd: Fix TCG OPAL unlock on system resume ... Commit 3cc2ffe5c1 ("scsi: sd: Differentiate system and runtime start/stop management") introduced the manage_system_start_stop scsi_device flag to allow libata to indicate to the SCSI disk driver that nothing should be done when resuming a disk on system resume. This change turned the execution of sd_resume() into a no-op for ATA devices on system resume. While this solved deadlock issues during device resume, this change also wrongly removed the execution of opal_unlock_from_suspend(). As a result, devices with TCG OPAL locking enabled remain locked and inaccessible after a system resume from sleep. To fix this issue, introduce the SCSI driver resume method and implement it with the sd_resume() function calling opal_unlock_from_suspend(). The former sd_resume() function is renamed to sd_resume_common() and modified to call the new sd_resume() function. For non-ATA devices, this result in no functional changes. In order for libata to explicitly execute sd_resume() when a device is resumed during system restart, the function scsi_resume_device() is introduced. libata calls this function from the revalidation work executed on devie resume, a state that is indicated with the new device flag ATA_DFLAG_RESUMING. Doing so, locked TCG OPAL enabled devices are unlocked on resume, allowing normal operation.
