Subject: media: amphion: Stop direct calls to queue num_buffers field
Author: Benjamin Gaignard <benjamin.gaign...@collabora.com>
Date: Thu Nov 9 17:29:22 2023 +0100
Use vb2_get_num_buffers() to avoid using queue num_buffers field directly.
This allows us to change how the number of buffers is computed in the
future.
