[merged mm-stable] drm-sti-dont-use-gfp_dma-when-calling-dma_alloc_wc.patch removed from -mm tree

[Andrew Morton]

The quilt patch titled
     Subject: drm/sti: don't use GFP_DMA when calling dma_alloc_wc()
has been removed from the -mm tree.  Its filename was
     drm-sti-dont-use-gfp_dma-when-calling-dma_alloc_wc.patch

This patch was dropped because it was merged into the mm-stable branch
of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm

Subject: drm/sti: don't use GFP_DMA when calling dma_alloc_wc()
Date: Thu,  3 Sep 2026 19:18:25 +0800

dma_alloc_wc() allocates the DMA buffer with the device's addressing
limitation in mind; the DMA core picks the zone from the device's coherent
DMA mask and ignores GFP_DMA passed by the caller.  Remove the redundant
GFP_DMA flag.
