From 9822504c1fa5c557ea8776765f03fd16eb4de4c9 Mon Sep 17 00:00:00 2001 From: Ard Biesheuvel Date: Mon, 25 Apr 2016 21:06:56 +0100 Subject: [PATCH] efifb: Enable the efi-framebuffer platform driver for ARM and arm64 Allows the efifb driver to be built for ARM and arm64. This simply involves updating the Kconfig dependency expression, and supplying dummy versions of efifb_setup_from_dmi().
