[PATCH 5.10 04/23] nvme-rdma: Use ibdev_to_node instead of dereferencing ->dma_device

From: Greg Kroah-Hartman
Date: Thu Feb 25 2021 - 05:08:24 EST


From: Christoph Hellwig <hch@xxxxxx>

commit 22dd4c707673129ed17e803b4bf68a567b2731db upstream.

->dma_device is a private implementation detail of the RDMA core. Use the
ibdev_to_node helper to get the NUMA node for a ib_device instead of
poking into ->dma_device.
