4.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Hans Verkuil <hans.verkuil@xxxxxxxxx>
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.
