[PATCH] wireless: move zd1201 where it belongs
zd1201 is wifi adapter, yet it is hiding in drivers/usb/net where noone can find it. This moves Kconfig/Makefile zd1201 to the right place. Signed-off-by: Pavel Machek <pavel@suse.cz> Signed-off-by: John W. Linville <linville@tuxdriver.com>

309 Say Y if you want to use wireless LAN adapters based on the ZyDAS
310 ZD1201 chip.
311
312 This driver makes the adapter appear as a normal Ethernet interface,
313 typically on wlan0.
314
315 The zd1201 device requires external firmware to be loaded.
316 This can be found at http://linux-lc100020.sourceforge.net/
317
318 To compile this driver as a module, choose M here: the
319 module will be called zd1201.
