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. Before: text data bss dec hex filename 34004 4388 320 38712 9738 gpu/drm/i915/gt/intel_reset.o After: text data bss dec hex filename 33528 4548 320 38396 95fc gpu/drm/i915/gt/intel_reset.o (gcc version 9.2.1, amd64) Signed-off-by: Colin Ian King <colin.king@canonical.com> Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk> Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Link: https://patchwork.freedesktop.org/patch/msgid/20191007154151.23245-1-colin.king@canonical.com
