Subject: drm/i915/gt: remove redundant assignment to variable dw
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=5d8b134150af3227179a251e5a7b435d9a021026;p=linux.git

drm/i915/gt: remove redundant assignment to variable dw

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")
