From 69d7d95452b8964ccb6bf8a7295016f6c669aa53 Mon Sep 17 00:00:00 2001 From: Markus Mayer Date: Tue, 13 Feb 2018 12:40:38 -0800 Subject: [PATCH] memory: brcmstb: dpfe: properly mask vendor error bits We were printing the entire 32 bit register rather than just the lower 8 bits. Anything above bit 7 is reserved and may be any random value.
