From b96976c1a87bc48ddd5f32566c682cd376e4b785 Mon Sep 17 00:00:00 2001 From: Sakari Ailus Date: Wed, 20 Jul 2016 08:32:49 -0300 Subject: [PATCH] media: entity: Fix stream count check commit 41387a59c8fd55975c6a26cc12fc5c9ca61fcc0f upstream. There's a sanity check for the stream count remaining positive or zero on error path, but instead of performing the check on the traversed entity it is performed on the entity where traversal ends. Fix this.
