From ba1f665f161ce112a2703649317bfdc9b6521613 Mon Sep 17 00:00:00 2001 From: Haneen Mohammed Date: Fri, 25 May 2018 04:25:55 +0300 Subject: drm: Add checks for atomic_[duplicate/destroy]_state with atomic drivers This patch add checks for atomic_[duplicate/destroy]_state of drm_[connector/crtc/plane]_funcs for atomic drivers in the relevant drm_*_init functions since these callback are mandatory for atomic drivers. Update the kerneldoc comments for those callbacks.
