"The userland callers are responsible for clearing the output buffers, so remove the unneeded memset calls." A driver should not assume that _userspace_ has cleared the buffers. In some cases userspace is supposed to clear certain fields, but you shouldn't assume it. AFAIK, for read-only ioctls there is no expectation at all that userspace will clear the buffer. Your patch is still right though, as now the videodev core will take care of this so individual drivers don't have to. -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
