From a24f56d47930492c94ef6875bf45adf7607ca1a4 Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Fri, 9 Dec 2016 11:28:19 -0200 Subject: [PATCH] [media] cec: CEC_MSG_GIVE_FEATURES should abort for CEC version < 2 This is a 2.0 only message, so it should return Feature Abort if the adapter is configured for CEC version 1.4. Right now it does nothing, which means that the sender will time out.
