[libcamera-devel] [PATCH 01/13] gstreamer: Use gst_task_resume() when available

The gst_libcamera_resume_task() helper is an implementation of the
gst_task_resume() function that predates its addition to GStreamer. Use
gst_task_resume() when available, and rename gst_libcamera_resume_task()
to gst_task_resume() to support older GStreamer versions.
