[Intel-gfx] [PATCH 1/4] drm/i915: Report -ENODEV after injecting probe failure

[Michal Wajdeczko]

We want to do more driver testing using injected load errors,
but we don't want to limit ourselves to use only -ENODEV (as
other errors are interpreted as real issues, like this:

<4> [381.569479] i915: probe of 0000:00:02.0 failed with error -7
