From: Stanimir Varbanov <stanimir.varbanov@xxxxxxxxxx> [ Upstream commit bc3d870e414b42d72cd386aa20a4fc3612e4feb7 ] Presently the list initialization is done only in dynamic-resolution-change state, which leads to list corruptions and use-after-free. Init list_head unconditionally in vdec_stop_capture called by vb2 stop_streaming without takeing into account current codec state.
