From 50fab0760a6c07cded229357a1351c325a575770 Mon Sep 17 00:00:00 2001 From: Alan Jenkins Date: Thu, 24 Sep 2009 20:15:24 +0100 Subject: sony-laptop: check for rfkill hard block at load time "I recently (on a flight) I found out that when I boot with the hard-switch activated, so turning off all wireless activity on my laptop, the state is not correctly announced in /dev/rfkill (reading it with rfkill command, or my own gnome applet)... After turning off and on again the hard-switch the events were right." We can fix this by querying the firmware at load time and calling rfkill_set_hw_state().
