[PATCH 2/2] drm/panic: Restrict graphical logo handling to built-in

[Geert Uytterhoeven]

When CONFIG_DRM_PANIC=y, but CONFIG_DRM=m:

    ld: drivers/gpu/drm/drm_panic.o: in function `drm_panic_setup_logo':
    drivers/gpu/drm/drm_panic.c:99: multiple definition of `init_module'; drivers/gpu/drm/drm_drv.o:drivers/gpu/drm/drm_drv.c:1079: first defined here

Fix this by restricting the graphical logo handling and its
device_initcall() to the built-in case.  Logos are freed during late
kernel initialization, so they are no longer available at module load
time anyway.

Fixes: 294bbd1f2697ff28 ("drm/panic: Add support for drawing a monochrome graphical logo")
