Subject: [PATCH 06/10] drivers/usb: Use ARCH_DMA_MINALIGN instead of ARCH_KMALLOC_MINALIGN
Date: Tue,  5 Apr 2022 14:57:54 +0100	[thread overview]
Message-ID: <20220405135758.774016-7-catalin.marinas@arm.com> (raw)
In-Reply-To: <20220405135758.774016-1-catalin.marinas@arm.com>

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