From 419dd8378dfa32985672ab7927b4bc827f33b332 Mon Sep 17 00:00:00 2001 From: Oleg Nesterov Date: Tue, 23 Jan 2007 20:04:13 -0300 Subject: V4L/DVB (5123): Buf_qbuf: fix: videobuf_queue->stream corruption and lockup We are doing ->buf_prepare(buf) before adding buf to q->stream list. This means that videobuf_qbuf() should not try to re-add a STATE_PREPARED buffer.
