Message-ID: <20250325210517.2097188-1-bradynorander@gmail.com> Date: Tue, 25 Mar 2025 17:05:17 -0400 From: Brady Norander <bradynorander@...il.com> To: dri-devel@...ts.freedesktop.org, amd-gfx@...ts.freedesktop.org, linux-kernel@...r.kernel.org Cc: alexander.deucher@....com, christian.koenig@....com, airlied@...il.com, simona@...ll.ch, sunil.khatri@....com, boyuan.zhang@....com, Brady Norander <bradynorander@...il.com> Subject: [PATCH] drm/amdgpu: use static ids for ACP platform devs mfd_add_hotplug_devices() assigns child platform devices with PLATFORM_DEVID_AUTO, but the ACP machine drivers expect the platform device names to never change. Use mfd_add_devices() instead and give each cell a unique id.
