+Subject: [PATCH] Fix link failure with gcc 10
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Without the 'extern' this looks like a definition not just a
+declaration, in every file that includes the header. gcc 10 is stricter
+about this kind of multiple definition.

+Upstream-Status: Backport [https://cgit.freedesktop.org/xorg/driver/xf86-video-ati/commit/?id=f223035f4ffcff2a9296d1e907a5193f8e8845a3]
