From 053ffcca0617aea9facd664adae133fb073e52a7 Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Tue, 21 Jun 2022 22:47:53 +0300 Subject: 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.
