In the platform with a limited backup power supply, devices like NVMe SSD does unsafe shutdown.
These two patches address this issue by adding a power loss imminent flag. The platform will enable the power loss imminent flag if the platform's power is running on the limited backup power supply. During the shutdown, the driver checks this information and pwerforms the abrupt shutdown.
