[PATCH 20/55] media: sunxi: sun6i-csi: Stop abusing of min_buffers_needed field

From: Benjamin Gaignard
Date: Mon Nov 27 2023 - 11:56:48 EST


'min_buffers_needed' is suppose to be used to indicate the number
of buffers needed by DMA engine to start streaming.
sun6i-csi 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.
