If a QAT device is not shutdown properly, the device driver will fail to load in a newly rebooted kernel. This might result in output like the following after the kexec reboot: QAT: AE0 is inactive!! QAT: failed to get device out of reset c6xx 0000:3f:00.0: qat_hal_clr_reset error c6xx 0000:3f:00.0: Failed to init the AEs c6xx 0000:3f:00.0: Failed to initialise Acceleration Engine c6xx 0000:3f:00.0: Resetting device qat_dev0 c6xx 0000:3f:00.0: probe with driver c6xx failed with error -14 Implement the shutdown() handler that hooks into the reboot notifier list. This brings down the QAT device and ensures it is shut down properly.
