If anyone has any objections, please let me know. ------------------ From: Stanislaw Gruszka commit 6232c17438ed01f43665197db5a98a4a4f77ef47 upstream. 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.
