[PATCH] Wireless Extension dropped patchlet

	This tiny bit of the last WE-17 patch was lost between me and
you. I initially decided to wait to resubmit, but Chris Wedgwood
reported that the MadWifi driver needs it. Sorry for not having pushed
harder.
	I recreated this patch, and tested with 2.6.10-rc1, and Chris
tested it with MadWifi. Would you mind pushing that up to Linus ?

Changelog :
	o remove unneeded const
	o spelling + comments
