KMS drivers really should all be able to restore their display state on resume without fbcon helping out. So make this the default.
Since I'm not entirely foolish, make it only a default, which drivers can still override. That way when the inevitable regression report happens I can fix things up with a one-liner plus FIXME comment that someone should fix up the suspend/resume code in that driver. But at least all new drivers won't be broken by accident as soon as you turn off fbcon because "suspend/resume worked when I tested it". v2: Keep this for radeon because of commit 18c437caa5b18a235dd65cec224eab54bebcee65 Author: Alex Deucher <[email protected]> Date: Tue Nov 14 17:19:29 2017 -0500 Revert "drm/radeon: dont switch vt on suspend" Thanks to Michel Dänzer for pointing this one out.
