From 1bddf1b3ac021feb9dafcc2c6ef7018453e22589 Mon Sep 17 00:00:00 2001 From: Andrzej Hajda Date: Mon, 3 Jun 2013 05:16:13 -0300 Subject: [PATCH] [media] media: Rename media_entity_remote_source to media_entity_remote_pad Function media_entity_remote_source actually returns the remote pad to the given one, regardless if this is the source or the sink pad. Name media_entity_remote_pad is more adequate for this function.
