Instead of rename, it's better for you to keep the typo and add the
correct entry with the same value, like:

$ git diff
diff --git a/include/uapi/sound/snd_sst_tokens.h
b/include/uapi/sound/snd_sst_tokens.h
index 93392bedcc58..b7cc95d04928 100644
--- a/include/uapi/sound/snd_sst_tokens.h
+++ b/include/uapi/sound/snd_sst_tokens.h
@@ -213,8 +213,9 @@ enum SKL_TKNS {
        SKL_TKN_U32_LIB_COUNT,

+       SKL_TKN_MAX = SKL_TKN_U32_D0I3_CAPS,
 };

 #endif
