Subject: [PATCH v15 10/56] media: amphion: Stop direct calls to queue num_buffers field
Date: Thu,  9 Nov 2023 17:29:22 +0100	[thread overview]
Message-ID: <20231109163008.179152-11-benjamin.gaignard@collabora.com> (raw)
In-Reply-To: <20231109163008.179152-1-benjamin.gaignard@collabora.com>

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.
