Nit pick - suggest to use dev_warn for easy identification of the device.
Thanks,

Subject: [PATCH 1/2] drm/amdgpu: Warn when bad pages approaches 90% threshold
dmesg doesn't warn when the number of bad pages approaches the
threshold for page retirement. WARN when the number of bad pages
is at 90% or greater for easier checks and planning, instead of waiting
until the GPU is full of bad pages.
