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.
