From 01566808547b7ecc5017a741d50dead9e53f86fa Mon Sep 17 00:00:00 2001 From: Gavin Shan Date: Thu, 20 Jun 2013 13:20:54 +0800 Subject: [PATCH] powerpc/eeh: Make eeh_pe_get() public While processing EEH event interrupt from P7IOC, we need function to retrieve the PE according to the indicated EEH device. The patch makes function eeh_pe_get() public so that other source files can call it for that purpose. Also, the patch fixes referring to wrong BDF (Bus/Device/Function) address while searching PE in function __eeh_pe_get().
