+Description:
+               This file allows you to turn debug output from the st driver
+               off if you write a '0' to the file or on if you write a '1'.
+               Note that debug output requires that the module be compiled
+               with the #define DEBUG set to a non-zero value (this is the
+               default). If DEBUG is set to 0 then this file will not
+               appear in sysfs as its presence is conditional upon debug
+               output support being compiled into the module.
