Subject: [PATCH v3 03/14] PCI: Export pci_ats_disabled() as a GPL symbol to modules
Date: Thu, 21 Nov 2019 11:49:07 +0000	[thread overview]
Message-ID: <20191121114918.2293-4-will@kernel.org> (raw)
In-Reply-To: <20191121114918.2293-1-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.
