[PULL,39/60] exec/cpu: Have cpu_exec_realize() return a boolean

Commit Message

Philippe Mathieu-Daudé Nov. 6, 2023, 11:03 a.m. UTC

Following the example documented since commit e3fe3988d7 ("error:
Document Error API usage rules"), have cpu_exec_realizefn()
return a boolean indicating whether an error is set or not.
