No, you should read the commit message:
"issue a single line to dmesg after the reload ... to let the user know that a
reload has at least been attempted."
and drop your patch.
We issue that line unconditionally to give feedback to the user that the attempt
was actually tried. Otherwise, you don't get any feedback and you wonder whether
it is doing anything.
The prev and next revision:
"microcode revision: 0x%x -> 0x%x\n",
will tell you whether something got loaded or not.
