Subject: [PATCH] drm/xe/tlb: Init range tilemask err to zero
Date: Mon, 16 Mar 2026 16:20:04 +0000 [thread overview]
Message-ID: <20260316162003.64643-2-jonathan.cavitt@intel.com> (raw)
Initialize err = 0 in xe_tlb_inval_range_tilemask_submit to prevent a
possible uninitialized value return in the case where the tile_mask
somehow doesn't match any available tile ids.
This targets a static analysis issue.
