+Subject: [PATCH] libxml-mm: Fix function prototypes in function pointers
+
+This is now detected with latest clang16+
+
+Fixes
+error: incompatible function pointer types passing 'void (void *, void *, xmlChar *)' (aka 'void (void *, void *, unsigned char *)') to parameter of type 'xmlHashScanner' (aka 'void (*)(void *, void *, const unsigned char *)') [-Wincompatible-function-pointer-types]
+                xmlHashScan(r, PmmRegistryDumpHashScanner, NULL);
