Subject: [PATCH v2 24/36] media: rockchip: rkisp1: Fix misuse of min_buffers_needed field
Date: Mon,  4 Dec 2023 14:23:11 +0100	[thread overview]
Message-ID: <20231204132323.22811-25-benjamin.gaignard@collabora.com> (raw)
In-Reply-To: <20231204132323.22811-1-benjamin.gaignard@collabora.com>

'min_buffers_needed' is suppose to be used to indicate the number
of buffers needed by DMA engine to start streaming.
rkisp1 driver doesn't use DMA engine and just want to specify
the minimum number of buffers to allocate when calling VIDIOC_REQBUFS.
That 'min_reqbufs_allocation' field purpose so use it.
