From b9736299c427d5b3df7324e4469f9ce46793f943 Mon Sep 17 00:00:00 2001 From: Philipp Zabel Date: Fri, 11 Jul 2014 06:36:18 -0300 Subject: [PATCH] [media] coda: remove BUG() in get_q_data This allows us to get rid of the now superfluous v4l2_m2m_get_vq check in G_FMT. Also, we can use this to check the buffer type in G_SELECTION later.
