Subject: iwl4965: reset firmware after rfkill off
From: Stanislaw Gruszka <sgruszka@xxxxxxxxxx>
commit 788f7a56fce1bcb2067b62b851a086fca48a0056 upstream.
Using rfkill switch can make firmware unstable, what cause various
Microcode errors and kernel warnings. Reseting firmware just after
rfkill off (radio on) helped with that.
