   4 Subject: [PATCH 01/19] rt2x00: avoid introducing a USB dependency in the
   5  rt2x00lib module
   6
   7 As reported by Felix:
   8
   9 Though protected by an ifdef, introducing an usb symbol dependency in
  10 the rt2x00lib module is a major inconvenience for distributions that
  11 package kernel modules split into individual packages.
  12
  13 Get rid of this unnecessary dependency by calling the usb related
  14 function from a more suitable place.
