We're testing the wrong variable here, and anyway list_entry() never returns NULL. We already verified that the list is not empty. This was added by: 721f507b694f "V4L/DVB (12842): tm6000: avoid kernel panic while retrieving the filling buffer" Signed-off-by: Dan Carpenter <error27@xxxxxxxxx> --- It could be that this is really trying to check if it's the last item in the list? In that case the fix is more complicated. diff --git a/drivers/staging/tm6000/tm6000-video.c b/drivers/staging/tm6000/tm6000-video.c index ce0a089..cbd89ad 100644 --- a/drivers/staging/tm6000/tm6000-video.c +++ b/drivers/staging/tm6000/tm6000-video.c @@ -145,9 +145,6 @@ static inline void get_next_buf(struct tm6000_dmaqueue *dma_q, *buf = list_entry(dma_q->active.next, struct tm6000_buffer, vb.queue); - if (!buf) - return; - /* Cleans up buffer - Usefull for testing for frame/URB loss */ outp = videobuf_to_vmalloc(&(*buf)->vb); -- To unsubscribe from this list: send the line "unsubscribe kernel-janitors" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
