From 0ea18b40cdd382a8a338d02e06c4646c35bd753b Mon Sep 17 00:00:00 2001 From: Alex Williamson Date: Tue, 7 Apr 2015 11:14:38 -0600 Subject: [PATCH] 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.
