From fe8e86b11a343f7101df9af6f0a9a3704ac673cf Mon Sep 17 00:00:00 2001

Subject: [PATCH 1032/2940] drm/amd/display: fix compliler errors
[-Werror,-Wmissing-braces]
Initializing structures with { } is known to be problematic since
it doesn't necessararily initialize all bytes, in case of padding,
causing random failures when structures are memcmp().
This patch fixes the structure initialisation related compiler
error by memset.
