Subject: [patch -next 2/2] ath9k_htc: rare leak in ath9k_hif_usb_alloc_tx_urbs()
Date: Fri, 14 May 2010 16:52:37 +0200	[thread overview]
Message-ID: <20100514145237.GF17487@bicker> (raw)

This is obviously a small picky thing.  The original error handling code
doesn't free the most recent allocations which haven't been added to the
hif_dev->tx.tx_buf list yet.
