+Subject: [PATCH] spa-json: fix va_list APIs for different architectures
+
+The va_list type might not always be a pointer in some architectures, so we
+cannot guarantee it will be modified after using it for a second time in another
+function. This fixes the issue by using macros so args does not get copied, and
+always gets modified when using it more than once.
+
+Upstream-Status: Backport [https://gitlab.freedesktop.org/pipewire/wireplumber/-/commit/e429db7e8c266045aee25e153fb2308bd61fe233]
