Hi

Rob and Dave, I hope you can shed some light here.

It seems src/qxl_drmmode.c is based on xf86-video-modesetting code, also
calling CrtcRotate:
http://cgit.freedesktop.org/xorg/driver/xf86-video-modesetting/tree/src/drmmode_display.c

Until very recently, it also implemented those stub functions:
http://cgit.freedesktop.org/xorg/driver/xf86-video-modesetting/commit/src?id=91571cce03adc58a10b5d76307629efc7c994c3e

I wonder if xf86-video-modesetting will reach the same crash now (since it
also has no crtc->driverIsPerformingTransform).

maybe the call to CrtcRotate should be removed in both implementations?
