Subject[PATCH][next] drm/vmwgfx: remove redundant assignment to sub_res
Date
From: Colin Ian King <colin.king@canonical.com>

Variable sub_res is initialized to a value that is never read and it
is re-assigned later in a for-loop. The initialization is redundant
and can be removed.

Addresses-Coverity: ("Unused value")
