Subject: edac, highbank: Fix interrupt setup of mem and l2 controller
From: Robert Richter <[email protected]>
commit a72b8859fd3941cc1d2940d5c43026d2c6fb959e upstream.
Register and enable interrupts after the edac registration. Otherwise
incomming ecc error interrupts lead to crashes during device setup.
Fixing this in drivers for mc and l2.
