From 19f722adef1973a3177d852bc6dac1d24e0cebc1 Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Sun, 15 Sep 2019 21:54:05 +0200 Subject: [PATCH] gemini: dir685: Restore graphics One of the v4.19 patches had a bug, this is fixed upstream, but in OpenWrt we can fix it by just fixing the bug in the patch. We also need to augment the config file to select the CONFIG_DRM_FBDEV_EMULATION symbol. This restores the display controller on the DIR-685 to working state: penguin and graphics on the little screen with default OpenWrt install.
