# clang (quite rightly) complains fairly loudly about the newly added # mpc1_get_mpc_out_mux() function returning an uninitialized value if the # 'opp_id' checks don't pass. # # This may not happen in practice, but the code really shouldn't return # garbage if the sanity checks don't pass. # # So just initialize 'val' to zero to avoid the issue. # # Fixes: 110b055b2827 ("drm/amd/display: add getter routine to retrieve mpcc mux") # Cc: Josip Pavic <Josip.Pavic@amd.com> #
