Subject: drm: use for_each_endpoint_of_node macro in drm_of_find_possible_crtcs
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=7416f4e33b5e924baa030ddab1f261a0a85fa32e;p=openwrt%2Fstaging%2Fblogic.git

drm: use for_each_endpoint_of_node macro in drm_of_find_possible_crtcs

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