[PATCH 4.15 123/202] media: v4l2-compat-ioctl32.c: drop pr_info for unknown buffer type

From: Greg Kroah-Hartman
Date: Thu Feb 15 2018 - 11:17:03 EST


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.
