Subject: [PATCH v9 3/4] usb: sl811-hcd: Add PM_EVENT_POWEROFF into suspend callbacks
Date: Sun, 26 Oct 2025 00:09:04 -0500 [thread overview]
Message-ID: <20251026050905.764203-4-superm1@kernel.org> (raw)
In-Reply-To: <20251026050905.764203-1-superm1@kernel.org>
When the ACPI core uses hibernation callbacks for shutdown drivers
will receive PM_EVENT_POWEROFF and should handle it the same as
PM_EVENT_HIBERNATE would have been used.
Tested-by: Eric Naim <dnaim@cachyos.org>
