There are different bits used to convey the setting of the rfkill switch to the driver. The current driver only supports one of these possibilities. These changes were derived from the latest version of the vendor driver. This patch fixes the regression noted in kernel Bugzilla #14743. Signed-off-by: Larry Finger <Larry.Finger@xxxxxxxxxxxx> Reported-and-tested-by: Antti Kaijanmäki <antti@xxxxxxxxxxxxxx> Tested-by: Hin-Tak Leung <hintak.leung@xxxxxxxxx> Cc: Stable <stable@xxxxxxxx> --- John, After seeing the response from DaveM regarding your last push, I expect problems getting this into 2.6.33; however, it is a regression from 2.6.31 as noted in the Bug cited above.
