Subject: media: docs: Fix mem_offset name in multiplane example
Author: Matthijs Kooijman <matth...@stdin.nl>
Date: Thu Mar 14 17:06:07 2024 +0100
The v4l2_buffer type has an "offset" field, but the corresponding field
in the v4l2_plane type is called "mem_offset". Use the correct name in
this example.
