From b9dcb97b6c8076af3469c62feb1174ef525b81f7 Mon Sep 17 00:00:00 2001 From: Colin Ian King Date: Mon, 7 Oct 2019 16:41:51 +0100 Subject: [PATCH] drm/i915: make array hw_engine_mask static, makes object smaller Don't populate the array hw_engine_mask on the stack but instead make it static. Makes the object code smaller by 316 bytes.
