750afb08ca cross-tree: phase out dma_zalloc_coherent()
We already need to zero out memory for dma_alloc_coherent(), as such
using dma_zalloc_coherent() is superflous. Phase it out.

This change was generated with the following Coccinelle SmPL patch:

@ replace_dma_zalloc_coherent @
expression dev, size, data, handle, flags;
@@

-dma_zalloc_coherent(dev, size, handle, flags)
+dma_alloc_coherent(dev, size, handle, flags)

5719e5eb31 net: hinic: make functions set_ctrl0 and set_ctrl1 static
The functions set_ctrl0 and set_ctrl1 are local to the source and do
not need to be in global scope, so make them static.

Cleans up sparse warnings:
symbol 'set_ctrl0' was not declared. Should it be static?
symbol 'set_ctrl1' was not declared. Should it be static?
