From 97d814fe4f697791abfbe27e035f0b943c483243 Mon Sep 17 00:00:00 2001 From: Lijo Lazar Date: Tue, 30 Apr 2024 16:53:16 +0530 Subject: [PATCH] drm/amd/amdxcp: Use unique name for partition dev MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit amdxcp is a platform driver for creating partition devices. libdrm library identifies a platform device based on 'OF_FULLNAME' or 'MODALIAS'. If two or more devices have the same platform name, drm library only picks the first device. Platform driver core uses name of the device to populate 'MODALIAS'. When 'amdgpu_xcp' is used as the base name, only first partition device gets identified. Assign unique name so that drm library identifies partition devices separately. amdxcp doesn't support probe of partitions, it doesn't bother about modaliases.
