[libcamera-devel] [PATCH v4 06/11] test: media_device: Add test for acquire() and release()

[Niklas Söderlund]

The interfaces MediaDevice::{open,close}() are about to be made private,
replace them with a test of MediaDevice::{acquire,release}() instead.
The new test will implicitly tests the open() and close() methods as
they are about to be move inside acquire() and release() which will
remain public.
