From 54ca193310bbd33bdf8b2634b6a3115dd8665013 Mon Sep 17 00:00:00 2001 From: Gabor Juhos Date: Wed, 1 May 2013 17:17:29 +0200 Subject: [PATCH] rt2x00: rt2x00dev: use rt2x00dev->tx->limit The TX data queue is initialized already when the rt2x00lib_probe_hw() 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.
