+Subject: [PATCH 01/19] rt2x00: avoid introducing a USB dependency in the
+ rt2x00lib module
+
+As reported by Felix:
+
+Though protected by an ifdef, introducing an usb symbol dependency in
+the rt2x00lib module is a major inconvenience for distributions that
+package kernel modules split into individual packages.
+
+Get rid of this unnecessary dependency by calling the usb related
+function from a more suitable place.
+
