limiting times ath9k_htc devices are loaded

[bruce m beach <brucembeach@xxxxxxxxx>]

Hello

  When I plug in a ath9k_htc device, with a loaded driver, the driver
attemps to attach itself to the device and load firmware etc. ( of
course ). Does anyone know how I can tell the driver ( or kernel ) to
do this process only once, and ignore additional insertions of
ath9k_htc devices ?
