Using the for_each_... macro should make the code a bit shorter and
easier to read.

drm: add of_graph endpoint helper to find possible CRTCs2014-07-11T14:38:28ZRussell Kingrmk+kernel@arm.linux.org.uk2014-06-15T10:07:12Zurn:sha1:7e435aad38083f378ba7889d8b8fdcdbfe7088e7
Add a helper to allow encoders to find their possible CRTCs from the
OF graph without having to re-implement this functionality. We add a
device_node to drm_crtc which corresponds with the port node in the
DT description of the CRTC device.
We can then scan the DRM device list for CRTCs to find their index,
matching the appropriate CRTC using the port device_node, thus building
up the possible CRTC mask.
