Subject: [PATCH 4.9 46/88] media: v4l2-compat-ioctl32.c: drop pr_info for unknown buffer type
4.9-stable review patch. If anyone has any objections, please let me know.
------------------
From: Hans Verkuil <hans.verkuil@...co.com>
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.
