+Backport required to function properly with >=nvidia-drivers-560,

+Subject: [PATCH] Fix the ABI version check.
+
+The EGL_EXTERNAL_PLATFORM_VERSION_CHECK macro checks whether the given
+version is older than EGL_EXTERNAL_PLATFORM_VERSION_MAJOR/MINOR, not
+newer.
+
+That's correct for using it in EGL_EXTERNAL_PLATFORM_HAS, since it'll
+check whether the build-time version supports a given feature, but it's
+wrong for checking the ABI version that the driver reports.
+
+Instead, use EGL_EXTERNAL_PLATFORM_VERSION_CMP.
