Subject: [PATCH] drm/i915/selftests: Potential uninitialized return in live_reset_whitelist()
Date: Fri, 27 Apr 2018 14:06:16 +0000	[thread overview]
Message-ID: <20180427140616.GC19583@mwanda> (raw)

Smatch complains that "err" could be uninitialized at the end.  I don't
know the code well but that seems like a reasonable warning.
