Subject: build failure in linux-next: offb missing fb helpers

Hello,

I am seeing these errors:

[ 3825s]   AR      built-in.a
[ 3827s]   AR      vmlinux.a
[ 3835s]   LD      vmlinux.o

[ 3864s] ld: drivers/video/fbdev/offb.o:(.data.rel.ro+0x58): undefined
reference to `cfb_fillrect'
[ 3864s] ld: drivers/video/fbdev/offb.o:(.data.rel.ro+0x60): undefined

[ 3864s] ld: drivers/video/fbdev/offb.o:(.data.rel.ro+0x68): undefined
reference to `cfb_imageblit'

cfb_fillrect is provided by drivers/video/fbdev/core/cfbfillrect.c

It is compiled when CONFIG_FB_CFB_FILLRECT
drivers/video/fbdev/core/Makefile:obj-$(CONFIG_FB_CFB_FILLRECT)  += cfbfillrect.o

drivers/video/fbdev/Makefile:obj-$(CONFIG_FB_OF)               += offb.o
is compiled when CONFIG_FB_OF

It selects CONFIG_FB_CFB_FILLRECT
config FB_OF
        bool "Open Firmware frame buffer device support"
        depends on (FB = y) && PPC && (!PPC_PSERIES || PCI)
        select APERTURE_HELPERS
        select FB_CFB_FILLRECT
        select FB_CFB_COPYAREA
        select FB_CFB_IMAGEBLIT
        select FB_MACMODES

The config has FB_OF built-in and FB_CFB_FILLRECT modular
config/ppc64le/vanilla:CONFIG_FB_CFB_FILLRECT=m
config/ppc64le/vanilla:CONFIG_FB_CFB_COPYAREA=m
config/ppc64le/vanilla:CONFIG_FB_CFB_IMAGEBLIT=m
config/ppc64le/vanilla:CONFIG_FB_OF=y

It only depends on FB which mut be built-in for FB_OF
config FB_CFB_FILLRECT
        tristate
        depends on FB

Is select in kconfig broken?

Attachnig the config in question.

Thanks

Michal
