Subject: [PATCH v9 3/6] PCI/ACPI: Allow ACPI to be built without CONFIG_PCI set
Date: Fri, 14 Dec 2018 16:33:16 +0000 [thread overview]
Message-ID: <20181214163319.27479-4-okaya@kernel.org> (raw)
In-Reply-To: <20181214163319.27479-1-okaya@kernel.org>
We are compiling PCI code today for systems with ACPI and no PCI
device present. Remove the useless code and reduce the tight
dependency.
