Subject: [PATCH] drm/amd/display: Initialize stack variable
Date: Tue, 29 Dec 2020 11:57:40 -0500 [thread overview]
Message-ID: <20201229165740.519759-1-Rodrigo.Siqueira@amd.com> (raw)
From: Wesley Chalmers <Wesley.Chalmers@amd.com>
The stack variable "val" is potentially unpopulate it, so initialize it
with the value 0xf (indicating an invalid mux).
