Subject: rt2x00: rt2x00dev: use rt2x00dev->tx->limit
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=54ca193310bbd33bdf8b2634b6a3115dd8665013;p=linux-beck.git

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.
