6.10-stable review patch. If anyone has any objections, please let me know.
------------------
From: Arnaldo Carvalho de Melo acme@redhat.com
commit 00dc514612fe98cfa117193b9df28f15e7c9db9c upstream.
The -Wcast-function-type-mismatch option was introduced in clang 19 and its enabled by default, since we use -Werror, and python bindings do casts that are valid but trips this warning, disable it if present.
