Hi,
The attached patch removes the sysfs interface from iwl3945 and uses
the rfkill subsystem instead.
(like 4965/5000 already do).
----------------------------
Use the rfkill subsystem instead of the sysfs interface.

Can we have a non-damaged version of this patch?

Added clearing the STATUS_EXIT_PENDING bit while ifup.
ACK.
The attached patch removes the sysfs interface from iwl3945 and uses
the rfkill subsystem instead.
Use the rfkill subsystem instead of the sysfs interface.
