From 84e680980917df60210af713e39400752dc4763d Mon Sep 17 00:00:00 2001 From: Philipp Zabel Date: Thu, 19 Sep 2013 04:53:21 -0300 Subject: [PATCH] [media] v4l2-mem2mem: clear m2m queue ready counter in v4l2_m2m_streamoff v4l2_m2m_streamoff drops the list of ready buffers but failed to reset the num_rdy counter to zero. This would lead to v4l2_m2m_num_src/dst_bufs_ready reporting wrong values after streamoff.
