i think it no need to be init, it just a list-entry.
Okay, if that's really the case, then sh_mobile_ceu_camera.c, pxa_camera.c, mx1_camera.c, mx2_camera.c, and omap1_camera.c needs to be fixed to remove that WARN_ON(!list_empty(&vb->queue)); in their videobuf_prepare() methods, because those WARN_ON's are assuming that vb->queue is properly initialized as a list head.
Which will it be?
yes, i think those WARN_ONs are no need.
