Hello,
the problem is described in the following patch.
Some remarks: I'm not quite sure if the function proposed in the patch should be placed somewhere else in the code... The patch now calls it during device deinitialization after urbs deallocation, and I suppose the interrupt callback ath9k_hif_usb_rx_stream() not to be executed during/after that period (in this case the leak would still remain, but I couldn't reproduce this particular case). Maybe the function freeing remain_skbs should be placed right before calling 'kfree(hif_dev)'?
The patch is made on top of [1] master branch.

--- Regards,
Fedor
