Nikita Zhandarovich 86238603c8 drm/i915/guc: prevent a possible int overflow in wq offsets ... [ Upstream commit d3d37f7468 ] It may be possible for the sum of the values derived from i915_ggtt_offset() and __get_parent_scratch_offset()/ i915_ggtt_offset() to go over the u32 limit before being assigned to wq offsets of u64 type. Mitigate these issues by expanding one of the right operands to u64 to avoid any overflow issues just in case. Found by Linux Verification Center (linuxtesting.org) with static analysis tool SVACE.
