- 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.
