From 529277121bba76f01fa75093b742b8429a067471 Mon Sep 17 00:00:00 2001 From: John Stultz Date: Tue, 20 Aug 2019 23:06:11 +0000 Subject: [PATCH] drm: kirin: Move workqueue to ade_hw_ctx structure The workqueue used to reset the display when we hit an LDI underflow error is ADE specific, so since this patch series works to make the kirin_crtc structure more generic, move the workqueue to the ade_hw_ctx structure instead.
