-Subject: [PATCH] lantiq_etop: pass struct device to DMA API functions
-
-The DMA API generally relies on a struct device to work properly, and
-only barely works without one for legacy reasons.  Pass the easily
-available struct device from the platform_device to remedy this.
-
-Note this driver seems to lack dma_unmap_* calls entirely, but fixing
-that is left for another time.
