From 20405c08412a4d89357870d7220f9fb1c458b286 Mon Sep 17 00:00:00 2001 From: Michael Buesch Date: Thu, 27 Sep 2007 21:34:23 +0200 Subject: [RFKILL]: Add support for hardware-only rfkill buttons Buttons that work directly on hardware cannot support the "user_claim" functionality. Add a flag to signal this and return -EOPNOTSUPP in this case. b43 is such a device. Signed-off-by: Michael Buesch Acked-by: Ivo van Doorn Signed-off-by: John W. Linville Signed-off-by: David S.
