Subject: [PATCH v2 6/6] iommu: Delete iommu_dev_has_feature()
Date: Wed, 6 Jan 2021 21:35:11 +0800 [thread overview]
Message-ID: <1609940111-28563-7-git-send-email-john.garry@huawei.com> (raw)
In-Reply-To: <1609940111-28563-1-git-send-email-john.garry@huawei.com>
Function iommu_dev_has_feature() has never been referenced in the tree,
and there does not appear to be anything coming soon to use it, so delete
it.
