base:   git://people.freedesktop.org/~airlied/linux.git drm-next
reproduce:
        # apt-get install sparse
        make ARCH=x86_64 allmodconfig
        make C=1 CF=-D__CHECK_ENDIAN__


sparse warnings: (new ones prefixed by >>)

>> drivers/gpu/drm/xen/xen_drm_front_kms.c:276:22: sparse: symbol 
>> 'display_mode_valid' was not declared. Should it be static?

Please review and possibly fold the followup patch.
