From f1bee783dd37d088a8a7924205476ba1cf675378 Mon Sep 17 00:00:00 2001 From: Florian Fainelli Date: Thu, 18 Sep 2014 12:32:10 -0700 Subject: [PATCH] bus: brcmstb_gisb: register the fault code hook Commit 44127b771d9c31 ("bus: add Broadcom GISB bus arbiter timeout/error handler") added everything that is required to register an ARM fault handler for imprecise external aborts, except that there is nothing calling this currently. We do not need to export that specific function and have to update arch/arm/mach-bcm/brcmstb.c to call it, simply, register the fault handler during the probe() function of the driver.
