#     drm/amd/display: avoid uninitialized variable warning
#     
#     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")
