From 862887d8836643e316cd019b93b1732971c8aaf8 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Sun, 8 May 2016 16:55:18 -0600 Subject: [PATCH] errno: Allow errno_str() to be used without CONFIG_ERRNO_STR The pmic framework uses errno_str() and this requires board that use it to enable CONFIG_ERRNO_STR to avoid a build error. Update the header to provide a NULL error message when CONFIG_ERRNO_STR is not defined, and fix the build error. This will show as "(null)" when U-Boot prints it.
