| |
-stable review patch. If anyone has any objections, please let us know.
------------------ 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.
(cherry picked from commit 419dd8378dfa32985672ab7927b4bc827f33b332)
