Subject: [PATCH v2 3/9] PCI: Export pci_ats_disabled() as a GPL symbol to modules
Date: Fri,  8 Nov 2019 15:16:02 +0000
Message-ID: <20191108151608.20932-4-will@kernel.org> (raw)
In-Reply-To: <20191108151608.20932-1-will@kernel.org>

Building drivers for ATS-aware IOMMUs as modules requires access to
pci_ats_disabled(). Export it as a GPL symbol to get things working.
