X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=67b43b9d7ced37a2e72e2c3e06464aa0a5be95f9;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

If dump is active during system reboot, shutdown or halt then invalidate
the fadump registration as it does not get invalidated automatically.
