All in all, this hunk does not really change anything from a functional point of view, so I'd like to suggest to omit this hunk completely instead to avoid code churn here. Thomas
[Qemu-devel] [PATCHv3 8/9] pseries: Clean up error reporting in ppc_spapr_init()
This function includes a number of explicit fprintf()s for errors. Change these to use error_report() instead. Also replace the single exit(EXIT_FAILURE) with an explicit exit(1), since the latter is the more usual idiom in qemu by a large margin.
