Rockchip just blew up here on testing, because I removed some "is this crtc already disabled/enabled" state tracking from callbacks (not needed with atomic). Turns out that was needed to work around rockchip still calling legacy helper code.
Since me explaining on irc/mailing-list plus kerneldoc isn't enough, be more verbose and add dmesg output. Not that anyone actually reads that, either.
