From: Peter Wu <peter at lekensteyn.nl> [ Upstream commit 7948a2b15873319d1bff4d37c09b9f2bf87b9021 ] "crtc->helper_private" is not initialized by the QXL driver and thus the "crtc_funcs->disable" call would crash (resulting in suspend failure). Fix this by converting the suspend/resume functions to use the drm_mode_config_helper_* helpers. Tested system sleep with QEMU 3.0 using "echo mem > /sys/power/state". During suspend the following message is visible f...

This patch set nukes all the dummy crtc mode_fixup implementations. (made on top of Daniel topic/drm-misc branch) Carlos Palminha (16): drm: fixes crct set_mode when crtc mode_fixup is null. drm/cirrus: removed optional dummy crtc mode_fixup function. drm/mgag200: removed optional dummy crtc mode_fixup function. drm/udl: removed optional dummy crtc mode_fixup function. drm/gma: removed

Hi! While trying to get CLUT support for the atmel_hlcdc driver, and specifically for the emulated fbdev interface, I received some push-back that my feeble in-driver attempts should be solved by the core. This is my attempt to do it right. I have obviously not tested all of this with more than a compile, but patches 1 and 3 are enough to make the atmel-hlcdc driver do what I need (when patched
