> Subject: [PATCH] drm/amdgpu: add uncorrectable error count print in UMC
> ecc irq cb
>
> Uncorrectable error count printing is missed when issuing UMC UE injection.
> When going to the error count log function in GPU recover work thread,
> there is no chance to get correct error count value by last error injection and
> print, because the error status register is automatically cleared after reading
> in UMC ecc irq callback. So add such message printing in UMC ecc irq cb to be
> consistent with other RAS error interrupt cases.
