From 3cbbb41049accbf2f6f6e79f6870f39b116cd585 Mon Sep 17 00:00:00 2001 From: Catalin Marinas Date: Mon, 12 Jun 2023 16:31:52 +0100 Subject: drivers/spi: use ARCH_DMA_MINALIGN instead of ARCH_KMALLOC_MINALIGN ARCH_DMA_MINALIGN represents the minimum (static) alignment for safe DMA operations while ARCH_KMALLOC_MINALIGN is the minimum kmalloc() objects alignment.
