This has led to reports [2] of compile errors like: In file included from drivers/gpu/drm/drm_edid.c:42:0: ./include/drm/drm_edid.h:525:2: error: initializer element is not constant ((((u32)((vend)[0]) - '@') & 0x1f) << 26 | \ Go back to the syntax I used in v4 of the patch series [3] that added this code instead of what landed (v5).
