[PATCH] cpu_ppc64: compare CPU function is ignoring return value

Function to compare CPU on 64-bit PowerPC is ignoring the flag to avoid failure in case of CPUs (host and guest) are incompatible. Basically, the function is returning -1 even if it is set to continue.

This would be easier to read with each of the if/else branches having their own return with the constant. No need to assing to ret just to return it in the next statement.

VIR_CPU_COMPARE_ERROR has the value of -1 Jano

Hi Jano, Your suggestion makes more sense. Let me send a V2 then. Tks :-) -- Julio Cesar Faracco Em ter., 27 de out. de 2020 às 12:24, Ján Tomko <jtomko@redhat.com> escreveu:
