Subject: drm/vmwgfx: Correctly set the enabled state on crtcs
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=c6c1f325adc8a8e0cd06c6ad0ca232a6880a1783;p=linux-beck.git

drm/vmwgfx: Correctly set the enabled state on crtcs

Failure to do this would make the drm_mode_get_crtc ioctl return
without crtc mode info, indicating that no mode was set.
