Johan Hovold 41a15855c1 efi: random: fix NULL-deref when refreshing seed ... Do not try to refresh the RNG seed in case the firmware does not support setting variables. This is specifically needed to prevent a NULL-pointer dereference on the Lenovo X13s with some firmware revisions, or more generally, whenever the runtime services have been disabled (e.g. efi=noruntime or with PREEMPT_RT).
