Subject: [PATCH v2 1/6] iommu: Export iommu_{get,put}_resv_regions()
Date: Tue, 16 Nov 2021 17:06:20 +0800 [thread overview]
Message-ID: <20211116090625.53702-2-yangyicong@hisilicon.com> (raw)
In-Reply-To: <20211116090625.53702-1-yangyicong@hisilicon.com>
Export iommu_{get,put}_resv_regions() to the modules so that the driver
can retrieve and use the reserved regions of the device.
