Subject: media: xilinx-vipp: Look for entities also in waiting_list
Author: Sakari Ailus <sakari.ai...@linux.intel.com>
Date: Fri Sep 29 09:31:08 2023 +0300
The big V4L2 async framework overhaul simplified linked lists used by the
V4L2 async framework. This affected a few drivers and it turns out a few
of those drivers rely on searching for entities in both async notifier's
waiting and done lists. Do that by separately traversing both.
Fixes: 9bf19fbf0c8b ("media: v4l: async: Rework internal lists")
