Thank you for prioritizing the fix!

There's another trivial issue which I just realized after sending out the
patchset. When "sock-priv" is a pointer (like the example below), ynl-gen
generates ugly code and fails scripts/checkpatch.

Should I use typedef instead although it seems discouraged according to
https://www.kernel.org/doc/html/latest/process/coding-style.html?

YAML:
+  sock-priv: struct binder_context *

==>

Generated code:
+void binder_nl_sock_priv_init(struct binder_context * *priv);
                                                     ^^^ extra space
+void binder_nl_sock_priv_destroy(struct binder_context * *priv);
                                                        ^^^ extra space
