Subject: [PATCH v9 03/14] swiotlb: Set dev->dma_io_tlb_mem to the swiotlb pool used
Date: Fri, 11 Jun 2021 23:26:48 +0800	[thread overview]
Message-ID: <20210611152659.2142983-4-tientzu@chromium.org> (raw)
In-Reply-To: <20210611152659.2142983-1-tientzu@chromium.org>

Always have the pointer to the swiotlb pool used in struct device. This
could help simplify the code for other pools.

Subject: [PATCH v9 03/14] swiotlb: Set dev->dma_io_tlb_mem to the swiotlb pool used
Date: Fri, 11 Jun 2021 23:26:48 +0800	[thread overview]
Message-ID: <20210611152659.2142983-4-tientzu@chromium.org> (raw)
In-Reply-To: <20210611152659.2142983-1-tientzu@chromium.org>

Always have the pointer to the swiotlb pool used in struct device. This
could help simplify the code for other pools.
