Subject: [PATCH] drm/i915/gt: remove redundant assignment to variable dw

From: Colin Ian King <colin.king@...onical.com>

Variable dw is being initialized with a value that is never read,
it is assigned a new value later on. The assignment is redundant
and can be removed.

Addresses-Coverity: ("Unused value")
