Subject: [PATCH V2 2/4] ath6kl: Fix htc_packet leak in ath6kl_htc_rx_fetch()
Date: Mon, 3 Oct 2011 17:28:25 +0530 [thread overview]
Message-ID: <1317643105-16139-1-git-send-email-vthiagar@qca.qualcomm.com> (raw)
It is found during the code review. As the leak would happen only
in failure case, the imapct is not easily visible.
