Mauro,
Function drivers/media/usb/em28xx/em28xx-video.c:get_next_buf
(copy pasted below for reference) does not take the list spinlock,
yet it modifies the list. Is that correct?
static inline struct em28xx_buffer *get_next_buf(struct em28xx *dev,
struct em28xx_dmaqueue *dma_q)
{
struct em28xx_buffer *buf;
if (list_empty(&dma_q->active)) {
em28xx_isocdbg("No active queue to serve\n");
return NULL;
}
/* Get the next buffer */
buf = list_entry(dma_q->active.next, struct em28xx_buffer, list);
/* Cleans up buffer - Useful for testing for frame/URB loss */
list_del(&buf->list);
buf->pos = 0;
buf->vb_buf = buf->mem;
return buf;
}
Thanks!
