Subject: [PATCH 1/4] nvme-pci: Set tagset nr_maps just once
Date: Thu, 3 Jan 2019 14:09:51 -0700 [thread overview]
Message-ID: <20190103210954.11129-1-keith.busch@intel.com> (raw)
The driver overwrites the intermediate nr_map assignments to
HCTX_MAX_TYPES, so remove those unnecessary temporary settings.
