  4. Subject: [PATCH 01/19] rt2x00: avoid introducing a USB dependency in the
  5. rt2x00lib module
  6. As reported by Felix:
  7. Though protected by an ifdef, introducing an usb symbol dependency in
  8. the rt2x00lib module is a major inconvenience for distributions that
  9. package kernel modules split into individual packages.
  10. Get rid of this unnecessary dependency by calling the usb related
  11. function from a more suitable place.
  12. Cc: Vishal Thanki <vishalthanki@gmail.com>
  13. Reported-by: Felix Fietkau <nbd@nbd.name>
  14. Fixes: 8b4c0009313f ("rt2x00usb: Use usb anchor to manage URB")
