From 59d35fe8f91857c74ab37e1f3eb79d7187908bf7 Mon Sep 17 00:00:00 2001 From: Harald Welte Date: Wed, 17 Feb 2016 19:28:03 +0100 Subject: [PATCH] Print error message if of_state_fixup() fails If of_state_fixup() fails for some reason, boot/bootm will fail, too However, it is completely unclear where the error has happened, and to the user it rather seems like the kernel device tree loaded from some file was broken/corrupt, not that in fact some fixup routine was failing. Adding a meaningful error message can help debugging significantly.
