From 3b640f21af4b6b36b546fecbd3fe5109981360da Mon Sep 17 00:00:00 2001 From: Ivo van Doorn Date: Sun, 3 Feb 2008 15:54:11 +0100 Subject: [PATCH] rt2x00: Enable LED class support for rt2500usb/rt73usb Add kerneldoc for vendor request functions in rt2x00usb. Add asynchroneous vendor request function in rt2x00usb. With the availability of the asynchroneuous vendor request we can now enable LED class support for rt2500usb and rt73usb. Since LED handling is not important, it doesn't really matter if a register call fails (This solution is better then no LED class support at all). Signed-off-by: Ivo van Doorn Signed-off-by: John W.
