Subject: [PATCH] drm/amd/display/dc/dce110/dce110_mem_input_v: use swap macro in program_size_and_rotation
Date: Fri, 10 Nov 2017 16:31:09 -0600 [thread overview]
Message-ID: <20171110223109.GA31549@embeddedor.com> (raw)
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.
