drm/amd/display: Initialize mode_select to 0
[ Upstream commit 592ddac93f8c02e13f19175745465f8c4d0f56cd ]
[WHAT]
mode_select was supposed to be initialized in mpc_read_gamut_remap but
is not set in default case. This can cause indeterminate
behaviors.
This is reported as an UNINIT error by Coverity.
