From 4f4d14b70a29c679dd53e367b0d9b007a7117ee3 Mon Sep 17 00:00:00 2001 From: Sylwester Nawrocki Date: Tue, 22 Jan 2013 18:58:57 -0300 Subject: [media] V4L: Add v4l2_event_subdev_unsubscribe() helper function Add a v4l2 core helper function that can be used as the subdev .unsubscribe_event handler. This allows to eliminate some boilerplate from drivers that are only handling the control events.
