If anyone has any objections, please let me know. ------------------ From: Hans Verkuil commit 169f24ca68bf0f247d111aef07af00dd3a02ae88 upstream. There is nothing wrong with using an unknown buffer type. So stop spamming the kernel log whenever this happens. The kernel will just return -EINVAL to signal this.
