Linville" Cc: linux-wireless@vger.kernel.org, users@rt2x00.serialmonkey.com, Gabor Juhos Subject: [PATCH 3/7] rt2x00: rt2800pci: use rt2x00dev->tx->limit Date: Wed, 1 May 2013 17:17:31 +0200 Message-Id: <1367421455-18463-4-git-send-email-juhosg@openwrt.org> (sfid-20130501_171826_599358_51F090D2) In-Reply-To: <1367421455-18463-1-git-send-email-juhosg@openwrt.org> References: <1367421455-18463-1-git-send-email-juhosg@openwrt.org> Sender: linux-wireless-owner@vger.kernel.org List-ID: The TX data queue is initialized already when the rt2800pci_txstatus_interrupt() function is called. Fetch the number of the queue entries from that instead of using the entry_num field of the data queue descriptor. The two values are the same, and the use of the rt2x00dev->tx->limit value allows us to get rid of a superfluous pointer dereference.
