Subject: [PATCH v10 2/3] scsi: Add PM_EVENT_POWEROFF into suspend callbacks
Date: Wed, 12 Nov 2025 16:40:24 -0600	[thread overview]
Message-ID: <20251112224025.2051702-3-superm1@kernel.org> (raw)
In-Reply-To: <20251112224025.2051702-1-superm1@kernel.org>

If the PM core uses hibernation callbacks for powering off the
system, drivers will receive PM_EVENT_POWEROFF and should handle
it the same as they previously handled PM_EVENT_HIBERNATE.

Support this case in the scsi driver.  No functional changes.
