Subject: stop drivers from passing GFP_COMP to dma_alloc_coherent
Date: Sun, 13 Nov 2022 17:35:28 +0100	[thread overview]
Message-ID: <20221113163535.884299-1-hch@lst.de> (raw)

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.
