Date: Wed, 18 Mar 2015 14:13:12 -0600 From: Alex Williamson <alex.williamson@...hat.com> To: alex.williamson@...hat.com, kvm@...r.kernel.org Cc: linux-pci@...r.kernel.org, bsd@...hat.com, linux-kernel@...r.kernel.org Subject: [PATCH v2 1/6] vgaarb: Stub vga_set_legacy_decoding() vga_set_legacy_decoding() is defined in drivers/gpu/vga/vgaarb.c, which is only compiled with CONFIG_VGA_ARB. A caller would therefore get an undefined symbol if the VGA arbiter is not enabled.
