Subject: [PATCH 50/55] media: pci: cx88: Use min_dma_buffers_needed field
Date:   Mon, 27 Nov 2023 17:54:49 +0100

cx88 driver use a dma engine and needs a minimum number of
buffers to be present before start streaming.
That is 'min_dma_buffers_needed' purpose so use it instead
of 'min_buffers_needed' field.
