I'm looking at drivers/media/video/videobuf-dma-contig.c's __videobuf_alloc() routine. We call kzalloc() to allocate the videobuf_buffer. However, I don't see where the two lists (vb->stream and vb->queue) that are a part of struct videobuf_buffer get initialized (with, say, INIT_LIST_HEAD).
This results in a warning in the V4L2 camera host driver that I'm developing when the buf_prepare method gets called. I do a similar sanity check to the sh_mobile_ceu_camera driver (WARN_ON(!list->empty(&vb->queue));) in my buf_prepare method, and see the warning. If I add INIT_LIST_HEAD to __videobuf_alloc(), this warning goes away. Is this a known bug? ----------------------------------------------------------------------------------- This email message is for the sole use of the intended recipient(s) and may contain confidential information.
