From 317b3c2167f5326a7de30a1abe50c9897da7a0e3 Mon Sep 17 00:00:00 2001 From: "Antonino A. Daplas" Date: Tue, 17 Jul 2007 04:05:28 -0700 Subject: fbdev: detect primary display device Add function helper, fb_is_primary_device(). Given struct fb_info, it will return a nonzero value if the device is the primary display. Currently, only the i386 is supported where the function checks for the IORESOURCE_ROM_SHADOW flag.
