Following condition which will cause NULL pointer dereference will occur in nvme_free_host_mem() when it tries to remove pci device via nvme_remove() especially after a failure of host memory allocation for HMB. "(host_mem_descs == NULL) && (nr_host_mem_descs != 0)" It's because __nr_host_mem_descs__ is not cleared to 0 unlike __host_mem_descs__ is so.
