drm/radeon: Resume fbcon last

2014-05-30T23:19:51Z

So a few people complained that commit 177cf92de4aa97ec1435987e91696ed8b5023130 Author: Daniel Vetter Date: Tue Apr 1 22:14:59 2014 +0200 drm/crtc-helpers: fix dpms on logic which was merged into 3.15-rc1, broke resume on radeons. Strangely git bisect lead everyone to commit 25f397a429dfa43f22c278d0119a60a343aa568f Author: Daniel Vetter Date: Fri Jul 19 18:57:11 2013 +0200 drm/crtc-helper: explicit DPMS on after modeset which was merged long ago and actually part of 3.14. Digging deeper I've noticed (again) that the call to drm_helper_resume_force_mode in the radeon resume handlers was a no-op previously because everything gets shut down on suspend. radeon does this with explicit calls to drm_helper_connector_dpms with DPMS_OFF. But with 177c we now force the dpms state to ON, so suddenly resume_force_mode actually forced the crtcs back on. This is the intention of the change after all, the problem is that radeon resumes the fbdev console layer _before_ restoring the display, through calling fb_set_suspend. And fbcon does an immediate ->set_par, which in turn causes the same forced mode restore to happen. Two concurrent modeset operations didn't lead to happiness. Fix this by delaying the fbcon resume until the end of the readeon resum functions. v2: Fix up a bit of the spelling fail.

Pull ACPI and power management fixes from Rafael Wysocki: "These are three stable-candidate fixes, one for the ACPI thermal driver and two for cpufreq drivers. Specifics: - A workqueue is destroyed too early during the ACPI thermal driver module unload which leads to a NULL pointer dereference in the driver's remove callback. Fix from Aaron Lu. - A wrong argument is passed to devm_regulator_get_optional() in the probe routine of the cpu0 cpufreq driver which leads to resource leaks if the driver is unbound from the cpufreq platform device. Fix from Lucas Stach. - A lock is missing in cpufreq_governor_dbs() which leads to memory corruption and NULL pointer dereferences during system suspend/resume, for example.
