Subject: [PATCH v4 07/19] iommu/rockchip: Remove detach_dev callback
Date: Wed, 4 Jan 2023 20:57:13 +0800 [thread overview]
Message-ID: <20230104125725.271850-8-baolu.lu@linux.intel.com> (raw)
In-Reply-To: <20230104125725.271850-1-baolu.lu@linux.intel.com>
The IOMMU driver supports default domain, so the detach_dev op will never
be called. Remove it to avoid dead code.
