Subject: ath9k_htc: Fix RX URB reference count
X-Git-Tag: v2.6.35-rc1~473^2~460^2^2~41

ath9k_htc: Fix RX URB reference count

RX URBs are automatically freed when the reference
count drops to zero - this currently doesn't happen when
usb_kill_anchored_urbs() is called during unload.

Fix this by dropping the reference count by one during
initial submission.
