Pull NVMe fixes from Keith:
"nvme fixes for Linux 6.6
- nvme-tcp iov len fix (Varun)
- nvme-hwmon const qualifier for safety (Krzysztof)
- nvme-fc null pointer checks (Nigel)
- nvme-pci no numa node fix (Pratyush)
- nvme timeout fix for non-compliant controllers (Keith)"
* tag 'nvme-6.6-2023-09-14' of git://git.infradead.org/nvme:
nvme: avoid bogus CRTO values
nvme-pci: do not set the NUMA node of device if it has none
nvme-fc: Prevent null pointer dereference in nvme_fc_io_getuuid()
nvme: host: hwmon: constify pointers to hwmon_channel_info
nvmet-tcp: pass iov_len instead of sg->length to bvec_set_page()
