From 8745ca5efb2aad0b6591d9b8cd48573ea49c929d Mon Sep 17 00:00:00 2001 From: Jonathan Kim Date: Thu, 9 Oct 2025 10:48:09 -0400 Subject: [PATCH] drm/amdgpu: fix initialization of doorbell array for detect and hang Initialized doorbells should be set to invalid rather than 0 to prevent driver from over counting hung doorbells since it checks against the invalid value to begin with.
