drm/amd/display: fix the return of the uninitialized value in ret
Currently if stream->signal is neither SIGNAL_TYPE_DISPLAY_PORT_MST or SIGNAL_TYPE_DISPLAY_PORT then variable ret is uninitialized and this is checked for > 0 at the end of the function. Ret should be initialized, I believe setting it to zero is a correct default. Addresses-Coverity: ("Uninitialized scalar variable") Fixes: bd0c064c161c ("drm/amd/display: Add return code instead of boolean for future use") Reviewed-by: Harry Wentland <harry.wentland@amd.com> Signed-off-by: Colin Ian King <colin.king@canonical.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
