-Subject: [PATCH] MIPS: lantiq: 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.
-
-Also use GFP_KERNEL instead of GFP_ATOMIC as the gfp_t for the memory
-allocation, as we aren't in interrupt context or under a lock.
-
-Note that this whole function looks somewhat bogus given that we never
-even look at the returned dma address, and the CPHYSADDR magic on
-a returned noncached mapping looks "interesting".  But I'll leave
-that to people more familiar with the code to sort out.
