From d44da04682033ad4c34d97861aef8ad5f7a8c2b5 Mon Sep 17 00:00:00 2001 From: Seung-Woo Kim Date: Wed, 13 May 2015 04:25:25 -0300 Subject: [media] s5p-mfc: fix state check from encoder queue_setup MFCINST_GOT_INST state is set to encoder context with set_format only for capture buffer. In queue_setup of encoder called during reqbufs, it is checked MFCINST_GOT_INST state for both capture and output buffer. So this patch fixes encoder to check MFCINST_GOT_INST state only for capture buffer from queue_setup.
