Please just edit as you like then, I think that's quicker.
The version I sent was meant to have smaller object code as well, and
I didn't think we could rely on drm_fb_cma_helper.c being built without
CONFIG_DRM_FBDEV_EMULATION, but I see now that they are
independent as you say, so making them unconditional indeed gives
the simplest code.
