Subject: drm/i915: tune reset dmesg output a bit
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=f2d91a2c556479713abbefec237cad4bc1d54b0d;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

drm/i915: tune reset dmesg output a bit

We don't want any ERROR for simulated gpu hangs, otoh printing the
error code when the reset failed for real should be interesting.
