Subject: stop drivers from passing GFP_COMP to dma_alloc_coherent

Hi all,

this series fixes up various drivers that either try to get a compound
page from dma_alloc_coherent or more often just did a bit of cargo
cult copy and paste, and then warns about this flag passed in the
DMA layer instead of silently clearing it like done by ARM and dma-iommu
before.
