Merge tag 'block-6.14-20250207' of git://git.kernel.dk/linux

Pull block fixes from Jens Axboe:

 - MD pull request via Song:
      - fix an error handling path for md-linear

 - NVMe pull request via Keith:
      - Connection fixes for fibre channel transport (Daniel)
      - Endian fixes (Keith, Christoph)
      - Cleanup fix for host memory buffer (Francis)
      - Platform specific power quirks (Georg)
      - Target memory leak (Sagi)
      - Use appropriate controller state accessor (Daniel)

 - Fixup for a regression introduced last week, where sunvdc wasn't
   updated for an API change, causing compilation failures on sparc64.
