From 168de20f3b6ccefef0ff5757fa5310f47a95c2f0 Mon Sep 17 00:00:00 2001 From: Tom Rini Date: Sun, 1 Jul 2018 22:10:33 -0400 Subject: [PATCH] Revert "fw_printenv: Don't bail out directly after one env read error" As pointed out by Wolfgang Denk, the problem with this fix is that while interactive users will see that we have found one part of the environment failed and are using the other, progmatic use will not see this and can lead to problems.
