Yes, default y is considered very much not cool. Default for drivers
should always be n, including su

Hi
DRM_STM is 'default y' on ARCH_MULTIPLATFORM and it selects
FB_PROVIDE_GET_FB_UNMAPPED_AREA. This breaks fbdev mmap for me on
Raspberry Pi. mmap returns -ENOMEM.
Disabling DRM_STM gives me working mmap.
