However, I'm afraid that a future change at videobuf_dma_init could cause a breakage. IMO, if we do such change, the better would be to split videobuf_dma_init into two functions or to add a comment at the code warning that this should match the init done at videobuf_dma_init. > > dprintk(1,"%s: allocated at %p(%ld+%ld) & %p(%ld)\n", > __func__,vb,(long)sizeof(*vb),(long)size-sizeof(*vb), > > > -- > To unsubscribe from this list: send the line "unsubscribe linux-media" in > the body of a message to majordomo@xxxxxxxxxxxxxxx > More majordomo info at http://vger.kernel.org/majordomo-info.html -- Cheers, Mauro -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
