[PATCH] drm/i915: remove redundant variable hw_check

From: Colin King
Date: Thu Sep 14 2017 - 12:22:23 EST


From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

hw_check is being assigned and updated but is no longer being read,
hence it is redundant and can be removed.

Detected by clang scan-build:
"warning: Value stored to 'hw_check' during its initialization
is never read"

Fixes: f6d1973db2d2 ("drm/i915: Move modeset state verifier calls")
