Re: [PATCH 01/18] MIPS: lantiq: pass struct device to DMA API functions

Hi Christoph,

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.

Would you like this to go through the MIPS tree or elsewhere? If the
latter:
