Revision 61d791365b72a89062fbbea69aa61479476da946 authored by Linus Torvalds on 25 December 2020, 23:41:13 UTC, committed by Linus Torvalds on 25 December 2020, 23:41:13 UTC
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")
