From: Christoph Hellwig Date: Wed, 9 Nov 2022 07:23:05 +0000 (+0100) Subject: s390/ism: don't pass bogus GFP_ flags to dma_alloc_coherent X-Git-Tag: v6.6.17~5972^2~2 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=c08004eede4b2d8a42a9a14ee50904f47cb239a1;p=platform%2Fkernel%2Flinux-rpi.git s390/ism: don't pass bogus GFP_ flags to dma_alloc_coherent dma_alloc_coherent is an opaque allocator that only uses the GFP_ flags for allocation context control. Don't pass __GFP_COMP which makes no sense for an allocation that can't in any way be converted to a page pointer.
