Subject: [PATCH 03/13] Bluetooth: Fix drop of packets with invalid req_seq/tx_seq
Date: Mon, 31 May 2010 14:02:42 -0300 [thread overview]
Message-ID: <1275325372-5671-3-git-send-email-padovan@profusion.mobi> (raw)
In-Reply-To: <1275325372-5671-2-git-send-email-padovan@profusion.mobi>
We can't use an unsigned var since we are expecting negatives value
there too.
