Subject: drm: use for_each_endpoint_of_node macro in drm_of_find_possible_crtcs
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=7416f4e33b5e924baa030ddab1f261a0a85fa32e;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.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.
