From 37c554b3fe987f95d75a0a981ce204240756d851 Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Tue, 4 Feb 2020 19:19:22 +0100 Subject: [PATCH] media: mc-entity.c: use & to check pad flags, not == commit 044041cd5227ec9ccf969f4bf1cc08bffe13b9d3 upstream. These are bits so to test if a pad is a sink you use & but not ==. It looks like the only reason this hasn't caused problems before is that media_get_pad_index() is currently only used with pads that do not set the MEDIA_PAD_FL_MUST_CONNECT flag. So a pad really had only the SINK or SOURCE flag set and nothing else.
