+- workaround for hp scanjet 8200
+  As described in <https://bugzilla.novell.com/show_bug.cgi?id=840443>
+  when operating on a hp scanjet 8200 the avision driver gets stuck
+  in a loop trying to detect an ADF, even if none is present.
+  In order circumvent this issue, following workaround has been implemented:
+  1) create an option "enforce-no-adf" in the file avision.conf
+  2) patch the code in avision.c to make use of this option,
+     if the conditions that lead to the unsuccessful ADF search
+     (namely detection of NO ADF but reporting of SOME ADF type) is given.
+  Per default the new option is inactive by comment; activate at your own risk!
+  An upstream report was added to
+  <https://alioth.debian.org/tracker/index.php?func=detail&aid=314108&group_id=30186&atid=410366>
+- created patch110 for avision.conf
+- created patch111 for avision.c
+- introduced patch110 and patch111 into sane-backends.spec
