__wl1271_plt_stop is called from both wl1271_plt_stop and
wl1271_unregister_hw. While wl1271_plt_stop acquires a mutex,
wl1271_unregister_hw does not.

Fix this by calling wl1271_plt_stop instead of __wl1271_plt_stop from
wl1271_unregister_hw.

The sched_scan_(stop|start) ops fails to check for WL1271_STATE_OFF.
This can lead to a race where the driver tries to access the HW
while it's off.

Fix this by checking for WL1271_STATE_OFF before accessing the HW.

The wl1251 driver was generating the following warning:

If you want to use mesh support from mac80211 on a recent
kernel on 2.6.24 you'll run into a name clash when compiling
against include/linux/namei.h, so rename this routine.

/home/mcgrof/tmp/compat-wireless-3.2.5-1/net/mac80211/mesh_pathtbl.c: At top level:
/home/mcgrof/tmp/compat-wireless-3.2.5-1/net/mac80211/mesh_pathtbl.c:342:26: error: conflicting types for ‘path_lookup’
include/linux/namei.h:71:12: note: previous declaration of ‘path_lookup’ was here

Although this could sit as a separate patch in compat-wireless it seems
best to just merge upstream.

The comment states that the field is only used for rt61pci and rt73usb.
However, it is now used by rt2800pci and rt2800usb as well, so the
comment is not correct anymore.

We are getting more and more fields in struct rt2x00_dev that are
specific to one or two of the low-level drivers. Instead of putting
these fields inside the main structure and thus clobbering all low-level
drivers with these fields, introduce the concept of driver data inside
struct rt2x00_dev, whose size is indicated by the low-level driver and
which can be populated by the low-level driver.

The two orinoco mailing lists on sourceforge were set up many years
ago and are now more or less moribund.  I'd like to shut them down, so
I don't have to keep filtering the spam from them (which is most of
what comes through now).  In preparation, this patch removes the
reference to them from the MAINTAINERS file.  Any remaining discussion
of this approaching obsolete driver can go to the linux-wireless list.

There are situations where we don't have the
necessary rate control information yet for
station entries, e.g. when associating. This
currently doesn't really happen due to the
dummy station handling; explicitly disabling
rate control when it's not initialised will
allow us to remove dummy stations.
