From 93a01629c8bfd30906c76921ec986802d76920c6 Mon Sep 17 00:00:00 2001 From: "Mario Limonciello (AMD)" superm1@kernel.org Date: Mon, 8 Dec 2025 22:46:46 -0600 Subject: [PATCH] drm/amd: Fix unbind/rebind for VCN 4.0.5

Unbinding amdgpu has no problems, but binding it again leads to an error of sysfs file already existing. This is because it wasn't actually cleaned up on unbind. Add the missing cleanup step.
