Subject: [PATCH 3/4] mips: set DMA_ALIGNMENT instead of defining dma_alloc
Date: Mon,  8 Jan 2024 11:24:37 +0100	[thread overview]
Message-ID: <20240108102438.1318473-3-a.fatoum@pengutronix.de> (raw)
In-Reply-To: <20240108102438.1318473-1-a.fatoum@pengutronix.de>

<dma.h> will take care to define dma_alloc with DMA_ALIGNMENT as
alignment. As 32 is the default and may not be applicable to the used
processor, we define DMA_ALIGNMENT and drop the now duplicate code.
