[merged mm-stable] drivers-base-use-arch_dma_minalign-instead-of-arch_kmalloc_minalign.patch removed from -mm tree

[Andrew Morton]

The quilt patch titled
     Subject: drivers/base: use ARCH_DMA_MINALIGN instead of ARCH_KMALLOC_MINALIGN
has been removed from the -mm tree.  Its filename was
     drivers-base-use-arch_dma_minalign-instead-of-arch_kmalloc_minalign.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: drivers/base: use ARCH_DMA_MINALIGN instead of ARCH_KMALLOC_MINALIGN
Date: Mon, 12 Jun 2023 16:31:49 +0100

ARCH_DMA_MINALIGN represents the minimum (static) alignment for safe DMA
operations while ARCH_KMALLOC_MINALIGN is the minimum kmalloc() objects
alignment.
