Make the offb (Open Firmware frame buffer) driver tristate, i.e., so that it can be built as a loadable module. However, it still depends on the setting of DRM_OFDRM so that both of these drivers cannot be builtin at the same time nor can one be builtin and the other one a loadable module. Build-tested successfully with all combination of DRM_OFDRM and FB_OF. This fixes a build issue that Michal reported when FB_OF=y and DRM_OFDRM=m: powerpc64-linux-ld: drivers/video/fbdev/offb.o:(.data.rel.ro+0x58): undefined reference to `cfb_fillrect' powerpc64-linux-ld: drivers/video/fbdev/offb.o:(.data.rel.ro+0x60): undefined reference to `cfb_copyarea' powerpc64-linux-ld: drivers/video/fbdev/offb.o:(.data.rel.ro+0x68): undefined reference to `cfb_imageblit' Signed-off-by: Randy Dunlap <redacted> Suggested-by: Arnd Bergmann <arnd@arndb.de> Cc: Masahiro Yamada <masahiroy@kernel.org> Cc: Thomas Zimmermann <tzimmermann@suse.de> Cc: Michal Suchánek <redacted> Cc: linuxppc-dev@lists.ozlabs.org Cc: Daniel Vetter <redacted> Cc: Helge Deller <deller@gmx.de> Cc: linux-fbdev@vger.kernel.org Cc: dri-devel@lists.freedesktop.org
