+Subject: [PATCH 2764/4131] drm/amd/display/dc/core/dc_resource: use swap macro
+ in rect_swap_helper
+
+Make use of the swap macro instead of _manually_ swapping values
+and remove unnecessary variable temp.
+
+This makes the code easier to read and maintain.
+
+This code was detected with the help of Coccinelle.
