Subject: [PATCH 1/5] pci: export pcie_get_speed_cap and pcie_get_width_cap
Date: Mon, 25 Jun 2018 16:06:02 -0500 [thread overview]
Message-ID: <20180625210606.2736-2-alexander.deucher@amd.com> (raw)
In-Reply-To: <20180625210606.2736-1-alexander.deucher-5C7GfCeVMHo@public.gmane.org>
So drivers can use them. This can be used to replace
duplicate code in the drm subsystem.
