Subject: rt2x00: remove data_queue_desc struct
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=705802bf56b1b7a64e543805ba196a6e1fb80ec6;p=openwrt%2Fstaging%2Fblogic.git

rt2x00: remove data_queue_desc struct

If the queue_init callback is implemented
by a driver it gets used instead of the
data_queue_desc based initialization.

The queue_init callback is implemented for
each drivers now, so the old initialization
method is not used anymore. Remove the unused
data_queue_desc structure and all of the
related code.
