Merge branch 'nvme-5.4' of git://git.infradead.org/nvme into for-linus
Pull NVMe changes from Sagi: "This set consists of various fixes and cleanups: - controller removal race fix from Balbir - quirk additions from Gabriel and Jian-Hong - nvme-pci power state save fix from Mario - Add 64bit user commands (for 64bit registers) from Marta - nvme-rdma/nvme-tcp fixes from Max, Mark and Me - Minor cleanups and nits from James, Dan and John" * 'nvme-5.4' of git://git.infradead.org/nvme: nvme-rdma: fix possible use-after-free in connect timeout nvme: Move ctrl sqsize to generic space nvme: Add ctrl attributes for queue_count and sqsize nvme: allow 64-bit results in passthru commands nvme: Add quirk for Kingston NVME SSD running FW E8FK11.T nvmet-tcp: remove superflous check on request sgl Added QUIRKs for ADATA XPG SX8200 Pro 512GB nvme-rdma: Fix max_hw_sectors calculation nvme: fix an error code in nvme_init_subsystem() nvme-pci: Save PCI state before putting drive into deepest state nvme-tcp: fix wrong stop condition in io_work nvme-pci: Fix a race in controller removal nvmet: change ppl to lpp
