Hi Arnd,

With is change we can get below error. If MODULE is define.

drivers/video/fbdev/matrox/matroxfb_base.c: In function ‘initMatrox2’:
drivers/video/fbdev/matrox/matroxfb_base.c:1799:23: error: ‘hotplug’ 
undeclared (first use in this function)
   minfo->fbcon.flags = hotplug ? FBINFO_FLAG_MODULE : FBINFO_FLAG_DEFAULT;

Please check this.
