[PATCH 0/7] docs/abi: align userspace documentation with implementation

["Iván Ezequiel Rodriguez" <ivanrwcm25@gmail.com>]

Documentation and ABI alignment fixes found on v7.3-rc1 by comparing
userspace-api docs, kernel-doc blocks, and uapi headers against the
current implementation.

Patches 1-6 are documentation only. Patch 7 makes GPIO v2 return
-EOPNOTSUPP when EVENT_CLOCK_HTE is requested but no HTE provider is
available, matching the documented behaviour.

No functional ABI changes are intended beyond the GPIO errno correction.

Iván Ezequiel Rodriguez (7):
  docs: futex2: fix documented errno names for futex_waitv
  docs: landlock: fix ENOMSG condition in create_ruleset kernel-doc
  docs: gpio: note lineinfo padding must be zero filled
  docs: dma-buf-heaps: fix CMA heap name typo
  docs: vduse: align documentation with current uapi and driver
  docs: ioctl: fix stale NVMe registry entry and note N conflict
  gpio: cdev: return EOPNOTSUPP when HTE is unavailable
