From 5256e057f5c1b45d7f3d0effd9a5b4e6cb95d248 Mon Sep 17 00:00:00 2001 From: Ricardo Ribalda Date: Mon, 20 Jun 2016 09:47:23 -0300 Subject: [PATCH] [media] vb2: Merge vb2_internal_dqbuf and vb2_dqbuf After all the code refactoring, vb2_internal_dqbuf is only called by vb2_dqbuf. Since the function it is very simple, there is no need to have two functions.
