3.2.51-rc1 review patch. If anyone has any objections, please let me know.
------------------ From: Stanislaw Gruszka <[email protected]> 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.
