From e67fbbec74220733971b88804be93528f5246434 Mon Sep 17 00:00:00 2001 From: Oliver O'Halloran Date: Fri, 15 Feb 2019 11:48:12 +1100 Subject: [PATCH] powerpc/eeh_cache: Add pr_debug() prints for insert/remove The EEH address cache is used to map a physical MMIO address back to a PCI device. It's useful to know when it's being manipulated, but currently this requires recompiling with #define DEBUG set. This is pointless since we have dynamic_debug nowdays, so remove the #ifdef guard and add a pr_debug() for the remove case too.
