+Subject: wacom: patch for testing
+Bug-Debian: http://bugs.debian.org/678798
+
+When rep_data was an array
+
+ unsigned char rep_data[2];
+
+spelling its address as &rep_data was perfectly valid, but now that
+it is dynamically allocated
+
+ unsigned char *rep_data = kmalloc(2, GFP_KERNEL);
+
+that expression returns a pointer to the pointer rather than to the
+array itself. Regression introduced by commit f393ee2b814e (Input:
+wacom - retrieve maximum number of touch points, 2012-04-29).
