From d50bae33d1358b909ade05ae121d83d3a60ab63f Mon Sep 17 00:00:00 2001 From: Larry Finger Date: Fri, 16 Oct 2009 10:18:09 -0500 Subject: [PATCH] b43: Fix Bugzilla #14181 and the bug from the previous 'fix' "b43: Fix PPC crash in rfkill polling on unload" fixed the bug reported in Bugzilla No. 14181; however, it introduced a new bug. Whenever the radio switch was turned off, it was necessary to unload and reload the driver for it to recognize the switch again. This patch fixes both the original bug in #14181 and the bug introduced by the previous patch. It must be stated, however, that if there is a BCM4306/3 with an rfkill switch (not yet proven), then the driver will need an unload/reload cycle to turn the device back on.
