You can't just change compatible strings.

Okay, maybe I should name all the compatible string with the suffix "-gmac" instead of
"-gemac". This can keep the compatible strings with the same suffix. Is this okay?
Can I just add the generic compatible string without changing the SoCs compatible string?
Like following:
        gmac0: ethernet@f9840000 {
 -              compatible = "hisilicon,hix5hd2-gmac";
 +              compatible = "hisilicon,hix5hd2-gmac", "hisilicon,hisi-gmac-v1";

Yes, this is fine.

As the patch series have been applied to net-next branch,
in which way should I commit this compatible fix?
Should I send a new patch fixing this compatible string error with "Fixes: xxx"?
Looking forward to your reply!

Yes to both.
