Follow-up to "[PATCH v2 0/4] drm/nouveau: fix list cursor use after loop
in the clk pstate paths" ([email protected]).
Sashiko AI review flagged three pre-existing issues while reviewing patch
2/4 of that series; the third (clk->func->prog()'s error being clobbered
by nvkm_volt_set_id() in nvkm_cstate_prog()) is already fixed by patch 4/4
of that series. These two patches address the other two:

  1. nvkm_pstate_prog() drops the RAM reclock error and falls through to
     core clock programming anyway.
  2. nvkm_pstate_prog() commits clk->pstate to the new state before the
     hardware transition has actually succeeded.

Francesco Magazzu (2):
  drm/nouveau/clk: don't ignore RAM clock programming errors in
    nvkm_pstate_prog
  drm/nouveau/clk: only update clk->pstate after hardware programming
    succeeds
