Subject: [PATCH v2 2/9] iommu/ioasid: Rename ioasid_set_data()
Date: Fri, 21 Aug 2020 21:35:11 -0700	[thread overview]
Message-ID: <1598070918-21321-3-git-send-email-jacob.jun.pan@linux.intel.com> (raw)
In-Reply-To: <1598070918-21321-1-git-send-email-jacob.jun.pan@linux.intel.com>

Rename ioasid_set_data() to ioasid_attach_data() to avoid confusion with
struct ioasid_set. ioasid_set is a group of IOASIDs that share a common
token.
