+we have added a patch for debian 10.  If you use the standard debian 10 kernel,eg:
+ * linux-image-4.19.0-17-amd64
+
+In debian release 10.11 the default kernel is:
+ * linux-image-4.19.0-18-amd64
+
+In this kernel there are some backports from kernel 5.4.0 and the driver does not
+compile anymore. SURF included a simple patch to fix this:
+ * cd src
+ * patch < debian10_patch
+
+This  patch compiles for old and new debian kernels
