Subject: [PATCH v5 08/16] swiotlb: Update is_swiotlb_active to add a struct device argument
Date: Thu, 22 Apr 2021 16:15:00 +0800	[thread overview]
Message-ID: <20210422081508.3942748-9-tientzu@chromium.org> (raw)
In-Reply-To: <20210422081508.3942748-1-tientzu@chromium.org>

Update is_swiotlb_active to add a struct device argument. This will be
useful later to allow for restricted DMA pool.

Subject: [PATCH v5 08/16] swiotlb: Update is_swiotlb_active to add a struct device argument
Date: Thu, 22 Apr 2021 16:15:00 +0800	[thread overview]
Message-ID: <20210422081508.3942748-9-tientzu@chromium.org> (raw)
In-Reply-To: <20210422081508.3942748-1-tientzu@chromium.org>

Update is_swiotlb_active to add a struct device argument. This will be
useful later to allow for restricted DMA pool.
