Subject: drm/amd/display/dc/dce110/dce110_mem_input_v: use swap macro in
program_size_and_rotation
Git-commit: 8aa111e34deedded58cd8576755f31659ba676f5
Patch-mainline: v4.16-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166
Make use of the swap macro instead of _manually_ swapping values
and remove unnecessary variable swap.
This makes the code easier to read and maintain.
This code was detected with the help of Coccinelle.
