[libgpiod][PATCH 0/7] teach libgpiod to read multiple line events at once

[Bartosz Golaszewski <brgl@xxxxxxxx>]

From: Bartosz Golaszewski <bgolaszewski@xxxxxxxxxxxx>

In v2 of my series adding the line status watch I introduced a regression
that made it impossible to read more than one event at the same time. This
is because I use libgpiod for testing and it doesn't allow to read more
than one event from user-space.

This series adds this missing functionality so that we can test v3 and avoid
this problem.

Bartosz Golaszewski (7):
  core: use gpiod_line_event_get_fd() in gpiod_line_event_read()
  core: provide functions for reading multiple line events at once
  tests: event: extend test coverage for reading multiple line events at
    once
  bindings: cxx: provide a method for reading multiple line events
  bindings: cxx: tests: add a test-case for reading multiple line events
  bindings: python: add a method for reading multiple line events
  bindings: python: tests: add a test-case for reading multiple line
    events
